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.
