You think that doesn’t happen to cis women? Cis straight women and girls?
Of course it does. I'm not the one pretending that trans kids are the only or most significant threat to womens' safety.
Who the hell is doing that?
The most controversial thing that I've done is to point out that for some women, being confronted by a naked person with a penis in a women's only space can be traumatizing. I would assume that if the cis woman or girl screamed, for both of them.
The reason that it can be traumatizing is because of sexual assault by men. Not because someone is trans. Not because someone is a prude. But because, if you grew up as a female, you'd know that we are conditioned from an early age to be very wary of naked penises in inappropriate contexts. Which has included until very very recently the understanding that means a naked penis in a women's only space would reasonably be considered inappropriate and a threat.
This says absolutely nothing about trans girls or women. It says a lot about rape culture in the US. And the fact that women, cis or trans, are pretty much left to defend ourselves against it.
So it should be no surprise if cis girls and women do exactly that: scream to raise the alarm. As we are conditioned to do.
Your solution is for us to give up all semblance of pretenses of privacy and have everything be universal for everyone. It sure isn't to give us any way to discern IN THE MOMENT that seems like an emergency that that person is just another woman.
Because that seems good to you. Inclusive.
It's not inclusive to women who require, for whatever reasons, more privacy. It's exclusive of such women and girls.
And you're ok with that. Because women who are religious or modest or who have been raped are all just anti-trans bigots.
