There is plenty of reasoned debate, and it is intolerant bigots who are "torn apart", using well-worn arguments. Transphobia, homophobia, misogyny, racism, etc all fall apart when their underlying intolerance and disgust is exposed. Transphobia is only unique amongst these examples because of the extreme asymmetry of numbers. "trans activists" or "TRA" are bullshit terms for any transgender person whose opinion you wish to invalidate, by framing us as 'an ideology' as opposed to 'people'
But that definition defines transphobia so widely that even asking questions about possibly conflicting rights has already been defined as transphobic. My comment was about the definition, its extreme scope, and the fact that it explicitly states that debate is unacceptable because it means questioning the transgender people's rights to exist.
It also suggests that defending women's sex-based rights (against sex-based oppression) is in itself transphobic, because any conflict of rights has been ruled out apriori.
So I managed to locate the link to the 'definition' by re-reading the whole thread, which was less than a pleasant experience. I hadn't come across it before, but have now saved it, so thank you. I hadn't read it when I wrote the comment you quoted, but my statement and their definition don't appear to conflict in any way.
I found the Trans Actual document to be concise, clear and informative.
I don't consider it over-broad, it just says "don't be an arsehole to transgender people"
I don't see how 'asking questions' would be problematic, when operating within the spirit of those guidelines.
As for 'defending women's sex-based rights against sex based oppression' you'd have to explain how they are attacked by trans people's rights.
From what I understand, by using the word 'sex' and not 'gender' they implicitly put themselves in opposition to trans rights so are designed to exclude trans women, so yes that would be problematic.
An interesting point made during IDEVAW was that if "sex based oppression" is biological rather than social (thereby excluding trans women, which was the point trying to be made), then there is no possible solution to it, which does seem like GC painting itself into a corner, TBH,
I'm sure there's words and definitions in there that some would quibble while I would take them at face value, so I'm OK with the document, whereas you might disagree.
