To save further derailment of the Sandie Peggie tribunal threads with people debating Tandora's statements on the above theme, I've started this thread to point them to instead.

Maybe this is Tandora's "research field" she works in.

The Bible. I won't say anything about the religious name.

What is the Cause of Gender Incongruence?
To put it bluntly, we don’t know (at least not firmly). Science and modern psychology has proven that it is not caused by nurture; no one becomes transgender, gender identity is congenital, solidifying before we even exit the womb. It also appears to sometimes be hereditary; transgender parents have a higher likelihood of having transgender children, and many times they realize this in reverse. The child comes out to the parent, and that helps the parent realize they can come out as well.

Here is the science that is believed to influence gender identity. This does not mean that it defines gender identity, nor does it fully encapsulate one’s gender, as so many aspects of gender are cultural and social. None of this is prescriptive of a person’s identity, none of it is cast in stone.

Science and modern psychology has proven that it is not caused by nurture; no one becomes transgender, gender identity is congenital, solidifying before we even exit the womb.

And they have "proven" this...how, exactly?

It also appears to sometimes be hereditary; transgender parents have a higher likelihood of having transgender children, and many times they realize this in reverse.

Given that this paper was based on only 27 sets of twins it may fall into the area of low quality 'evidence'.

It needs to be replicated elsewhere and with a minimum of 100 sets. (I'm only applying what NICE and researchers were telling me about research my own area of unrelated interest as a patient).

I'd also like to see a control group of gay twins to compare any results to in all trans research (just in case we are seeing gay people being misdiagnosed as Trans).

Trans people deserve proper research. Extraordinary claims need clear evidence.

also, Australia is very pro trans.

study should be replicated in areas where the bias towards affirming is much more balanced.

By someone who said 'gonads' but then said they actually meant reproductive system, whilst claiming to be an expert in these matters.

Who has said trans affects the brain (but no other part of the body) and then said it's not trans brains.

Who said that males with CAIS are never male but also said they are sometimes male.

That's not what I said at all on any front.

I'm here to have a productive exchange about the complexities of sex development and what that means for being trans and/ or having a DSD.

Anyone who is interested in that I'm happy to have a respectful exchange with.

You need to read beyond sentence 2:

*To increase the power of our analysis, we pooled our observations with previously published twin data that used comparable methods to ours. The pooled sample of 463 twin pairs comprised 47/222 (21.2%) MZ and 21/241 (8.7%) DZ concordant pairs. Based on a 1% population prevalence estimate, the estimated relative risk ratios for transgender concordance were 21.2 for MZ pairs (95%CI 16.4–27.3), and 8.7 for DZ pairs (95%CI 5.8–13.1).

teksquad · 24/07/2025 16:17

But you keep complaining that we wont agree with you so how is that a productive exchange?

suggestionsplease1 · 24/07/2025 13:44

Honesty posters on here crack me up:

"a rapidly growing cadre of people with perfectly good male or female bodies who have a mental issue with their self image and feelings."

"The above has now been clarified in law by the Supreme Court."

"Correct so far?"

😂😂😂

It is noticeable that you are very quick to say "no it's not that" and ridicule posters for what they say but very shy of saying what you think about sex and gender.

It's a clear pattern with Genderists. Never explain, only attack. Even Tandora, for all her words, is not saying what sex or gender is, only what it is not.

Anyone would think you are scared to put it clearly out there for everyone to see because you know it doesn't stand up.

But please, prove me wrong.

What is this difference between men amd women that is simultaneously so meaningful that we need to give these groups of humans different names and at times different rights, that leads to such population level differences in life outcomes, in physical and sexual aggression, in political and cultural representation and power? So mysterious snd elusive that it can never be observed only the self reported, and yet so much more meaningful then simple physical sex not just to the individual but also to those they interact with that this undefinable unperceivable quality overrides whatever actual sex they may observe such that a woman no longer experiences a man's hands on her as a man's but as a woman's, a man's sight on her not as a man's gaze but a woman's glance, a man speaking for her not as male dominance but female solidarity?

Yes the suggestion of a "trans" brain is silly. As is the suggestion of a "male" and "female" brain. Obviously human brains are more complex than that. As are human bodies in general.

Were you not just telling us that being trans is a hitherto undiscovered DSD found in the brain?

Hi @Tandora , Forgive me for not having read every post yet, it's a very long thread. Also a very interesting one. I'm genuinely curious about your perspective. Have a small question that might help me understand things better. How would you determine if a person is male or female?

@Tandora
You may have missed this. I think your answer here would help clarify some details. Would appreciate it.

Tandora · 24/07/2025 16:26

BackToLurk · 24/07/2025 15:46

It seems to me that every time @Tandora is asked about relevance to single-sex spaces, they disappear

First of all, this isn't true. I've clarified my opinion on single sex spaces multiple times.

However, I'm not obliged to debate with you on any subject you please.

I've repeatedly stated that my interest in engaging in conversations about sex/ gender/ transness is not because I want to have a debate about who gets to use what toilet. I couldn't be less interested in that, and I don't think it's helpful.

As I have explained repeatedly, it's impossible to have a reasonable discussion about policy when we can't even agree on the basics. In a context where there is so much misunderstanding about what being trans is, and so much prejudice towards trans people, that conversation is never going to reasonable.

So that is why I engage in these conversations. To try to challenge misunderstandings, prejudices related to understanding what 'sex' is, what 'gender' is, how they are related, and what it means to be trans or to have a DSD.

That is what I'm here to discuss. Not toilet arrangements, or security in prisons.

Accessing spaces wgere women are vulnerable (prisons/hospitals/changing rooms) or disadvantaged (sports) is what this boils down to.

and without clear delineation of what yhd male and female sexes are is what is needed

You can wax lyrical about how people ‘feel’ inside their heads and opine that theres a biological basis for those feelings all you want, but even if they do have a biological basis it doesn’t change the fact that people are objectively either male or female based on their sex - not their feelings, not how they’d prefer to present etc etc, but on actial reality.

I think your account must have been hacked then, because this username spent an enormous amount of time and energy trying to claim that the SC ruling would still allow trans women into women's spaces. You seemed extremely interested in the topic then. Pages and pages of it IIRC.

Or is this part of your recent Damascene conversion from Protector of the Trans to Champion of the DSD and "Researcher" in "The Field"?

I was thinking generally. To pick something more specific, perhaps, in the context of seeing a doctor? Maybe you could mention some contexts where it could differ as well?

How so exactly?

Exactly in the way that: why would you keep engaging, over multiple days, all day, all evening, despite it making you feel sick, if you are still merely TRYING to have a productive exchange and educate us into your way of thinking? If you're still TRYING to convince us, surely we're a lost cause? I think its clear that apart from one or 2 other posters, we aren't being convinced. So why keep going?

KateShugakIsALegend · 24/07/2025 16:45

Ok, to summarise, @Tandora and @suggestionsplease1 :

  • You feel that probably most or all (not sure which) trans people have a medical reason for being trans. Is this right?
  • You believe there is extensive research to support this view, but have yet to cite it or provide links. Is this right? Have I missed the links?
  • Is BeLemonNow's summary of your thinking on this point correct (page 27)?
  • You believe that the tiny percentage of people currently diagnosed with DSD fall within this group (see above) of trans people (or do you think they are a separate group?)

Please correct my understanding if incorrect.

Now here's the thing:

  • why does any of the above mean that this small percentage of trans women (men at birth) have a right to be in a space for women if women don't want them there?

Yes I believe the Supreme Court judgement has been widely wildly misinterpreted , and that misinterpretation needs urgently to be challenged as a matter of law.

I'm not interested in a broader conversation about who should have the right to use what toilet based on my opinion on that versus yours. It's not an interesting conversation, nor is it useful/ productive when there is still so much misunderstanding and prejudice directed at trans people.

It made me feel quite ill the thought that there are individuals determined to persistently and insistently impose the label "male" on women's with CAIS, yes. That attitude needs to be challenged - so challenge it I did.

There are many individual users who I don't bother reading posts from or replying to. There are some posters - a few - who engage in more interesting and productive ways - although tbf often that doesn't last.

I still think it's worth having the conversation, and when people ask me questions I think I can usefully reply to, I am driven to do so. For the sake of trans people, people living with DSDs and all humans in general.

@Tandora please, tell me why should I care whether a man 'thinks' he is a woman or whether a man has a 'medical' anomaly?

Why does either reason mean I should welcome him into my safe spaces?

This is the crux of the matter.

Why do you think you understand the law better than the country's finest legal experts?

Earlier you were claiming that your expertise in some mysterious and unspecified yet relevant area of scientific research means that you are more qualified to talk about biological sex than the rest of us.

Well...I'm a lawyer.

What would happen to individuals with CAIS if the medical profession decided that they were indeed female and couldn’t possibly be having a pile of testosterone running around their body that is useless to them, and thus there was no medical basis for them to receive necessary treatment - which would effectively leave them without sufficient sex hormones of any kind?

Whether someone is male or female isn't dependent on any context. The answer is the same in literally every context.
