ButterflyHatched I'm puzzled by your insistence on 'danger' and 'harm' and transpeople 'having sex with dangerous people who mean us harm' here on a board which is called Feminism/Women's Rights where 90.something% of your interlocutors are women. Biologically female, for the sake of clarity.
The element of danger and harm in intimate relationships has a very clear bias - 94.4% of perpetrators are male [UK 2024 stats].
So a transperson in a relationship [I'm not clear from your posts whether you are referring to sexual encounters, or longer relationships or both] is most likely to come to harm if they their partner is male.
If a transwomen, a.k.a. a biological male, sets their sights, unluckily, on a woman who turns out to be one of those awful GC terves - who experiences the harm? who is damaged? who is endangered?
If I was GC lesbian terf who was the object of a transwomen's attentions, and belatedly discovered the biological sex of my suitor, my reaction would be negative, but it would not be to do them any damage or harm; they would not be in any danger.
I, on the other hand, finding myself in a vulnerable situation with someone who I initially trusted, but have now found out belongs to the group which represents 94.4% of abusers of women like me - I'd be checking for a clear path to the door.
If you are arguing that transwomen who have sex with men are 'having sex with dangerous people who mean us harm' - well that's a whole other - and sadly familiar to us women - story about male violence, isn't it?
