Just doing a little research and thought, if anyone has seen the full range of reasons - it would be all of you!

Cos avocados. Can't stand avocados, they taste like soap. Must be a meaning in there somewhere?

Which female politician used that argument and then stated that their chromosomes were 'probably XY'?

Edit. In reply to Flunkit.

CrazyWorldBlues · 27/05/2026 10:41

Because of white-throated Sparrows

Flunkit · 27/05/2026 10:40

No one's checked my chromosomes

Because some women have smaller boobs than other women 🤔 (and are therefore less female).

No one has actually said that to me (that yardstick would make me female+++++) but if they did, I'd turn it around to penis size - 'so are you saying that a man with a big penis is more masculine than a man with a smaller one?' Preferably said in front of a large group of men for best effect, and then sit back and watch the blustering.

Yet breast size and shape do change a lot over the course of the female lifetime. Sadly, nay tragically, at 70+ I no longer have the breasts I had at 16, I can't deny it. And I'm every bit as female now as I was then (although much less inclined to take shit from anyone).

... because it was invented to benefit cis-heteronormative folx.

Also, no one can see your chromosomes, so they're not important in day to day life
Lots of things can't be seen, Marburg virus, gamma rays, Bacillus anthracis, carbon monoxide....I still take all of them fecking seriously.

Edited

You can't see my blood, my lungs, my brain...

I've never heard such nonsense.

“It’s a complex subject but essentially the science bit is that the template of the embryo in the womb is female and that then goes through a chemical washing process, But for transgender people it’s like the washing machine doesn’t quite fill up, which causes disparity in the brain"

😅🤣😂 this one wins 🏆

And 'everyone's sooo Obsessed with genitals. We need to stop using genitals as a sex marker!'

Scientific American says it's not ...
Here's Why Human Sex Is Not Binary | Scientific American
Are you saying you know better than Scientific American? Who do you think you are? (I'm a doctor by trade, so you're probably less qualified to talk about human biology than I am, and if you're equally or better qualified than I am to talk about human biology then you should fucking well be ashamed of yourself for getting sucked into claiming to believe in this gender bollocks. If you can use a can't win either way argument, so can I.)

I've also seen the "women's football got banned because the women were beating all the men" nonsense in the wild. Yes, right. So that'll be why, 100 years later, women with a lifetime of reasonable access to sporting opportunities and decent nutrition are absolutely walloping the men.

Ova don’t make a woman, and sperm don’t make a man

CorvusPurpureus · 27/05/2026 10:02

Because ‘well when women first started football, they got banned for beating all the men. No I’m not doing your homework - fact check it yourself. Also transmen develop beer guts in middle age so what with that & the beards you wouldn’t want them in your toilets WOULD YOU. & tall women exist, YOU are taller than lots of men, you wouldn’t like people calling you a man WOULD YOU’.

(a) it’s happened quite a lot albeit momentarily actually, & I’m fine with it (b) the ex friend in question is a 6’4 bloke who was towering over me whilst berating me for being tall…BUT FOOTBALL 😆

Me: "sex is binary"
Sibling (a biologist! recoiling in horror): "Good heavens! It's the 21st century"

Men can get breast cancer which means that men can breastfeed

sashh · 27/05/2026 09:45

That taking hormones changes their DNA.

Justme56 · 27/05/2026 09:20

I remember some young woman on X saying that with hormones women can grow a prostate. I guess this goes with the same idea that men can grow a cervix.

ApplebyArrows · 27/05/2026 09:08

An extremely intelligent man I knew well on another forum arguing, seriously, that sex was on a spectrum because different people have different levels of sex hormones.

You might as well argue that sex is on a spectrum because some men are shorter than some women!

SueKeeper · 27/05/2026 09:03

Because they've heard of a bimodal distribution and thank it sounds clever but don't realise you have to actually have something measurable along the x axis

Because binary sex is just a colonialist idea

HaveYouActuallyDoneAnyWashingThisWeekMum · 27/05/2026 07:37

CassOle · 26/05/2026 20:33

... because sex is a constellation of points.

🤭

Because…because…it’s actually really complex.

(from mother of identical twins) "The in utero hormone bath may have had a different balance from one twin vs. the other"

Sex is assigned at birth and doctors get it wrong sometimes and tick the wrong box

Heggettypeg · 26/05/2026 22:52

ManyShapesOfPasta · 26/05/2026 20:26

Because ancient roman times.
Yes, they really said that.

I missed that one! How is it supposed to work? Or didn't they say?

ElenOfTheWays · 26/05/2026 22:51

But but but ... intersex/sex is on s spectrum/not everyone is either male or female
Ladybrain/pink brains, blue brains
Because I said so.

Yep! We had lots of fun with that quote at the time!
