I know what you're describing OP: I've seen some of this online, the position that it is 'too triggering' for males who identify as women to have sexual relationships with other males who identify as women. Perfectly understandable and obviously personal needs and choices around sex should always be respected. Yet the relevant point to this thread is that this position is politically extended to mean it is therefore justifiable and socially acceptable that males who identify as women may openly state an exclusive preference for biological females for sexual relationships, while at the same time stating that it is unacceptable for biological women to state an exclusive preference for biological women in the same way, and this is framed as a serious fault and act of bigotry if they do so.
This inevitably raises questions and exposes some of the most anti woman and insulting/threatening illogic in the ideology, for example that this makes clear that it is perfectly possible for everyone to differentiate between biological males and biological females just as the human race has always done. And that in some situations, biology matters and it is appropriate and necessary to make a distinction and a choice.
So it then becomes simply about who is entitled to make those distinctions and who isn't, who is entitled to have choice and have their needs, feelings and preferences respected and who isn't, and therefore who has power and who doesn't. Because this forces inequality and oppression on women while trying to frame it a 'positive' social thing, and sets up a relationship of unequal power and unequal standards, which is the hallmark of a bullying and abusive relationship.
Note for the hard of thinking: this obviously in no way polices anyone's individual sexual choices and preferences, this is about the rights of women, and the threat to women in such political ideas. And the actual harassment being experienced by women, by males wishing to dictate and control their boundaries and rights.
And for the even harder of thinking: no you do not have to be a lesbian to be allowed to talk about homosexuality or a political assault on women's rights, and I'll be glad to help you locate a grip store.
