The newest tweet is getting the predictable 'bigots want to erase us' response.
The odd thing is that a transwoman who really, truly believed that TWAW would have no problem with the statement 'this survey is for women'. They'd fill it in, regardless of what GC women thought about that. If they're a woman, it's for them, right?
Wanting the 'identify as' line is something else. It's demanding the explicit acknowledgement that the organisation's stance is that womanhood is a feeling and that the survey is for anyone who thinks they have a ladybrain. Paradoxically, this very statement is drawing a distinction between actual women and men who identify as women in a way that 'this survey is for women' doesn't. And it's prioritising the latter.
It's politically charged and it also seems like a demand for a profession of faith. Phrase it in just the right way, or you're not one of us. (See also: pronouns always being listed as 'she/her' instead of just 'she', even though there's never going to be any confusion that someone might actually want 'she/him')
