"Lesbian sex party"
I wonder how many dicks would be bulging under the dresses in that "lesbian party", like really, I doubt any of the people in that party would've been a non-trans person.
The funny thing is that technically it's now possible for men to wear dresses and get real lesbians have sex with them. Turning the offer down after turning up and seeing the reality would be transphobic so the lesbian girl would have to join in. And on the other hand if some girl has a fetish for men who wear dresses and would like to have sex with them, she couldn't be honest about it and say it's a fetish but she would have to act as if they are women no matter how much beard and muscles they have.
"Hey fellow girl there, girls making out with other girls is refreshing and empowering isn't it? What would you say, would you try it out with me? You are a girl and I am a girl (and don't you ever say I am not a girl!!!) so there are no scary men to be dealt with but just two cute girls messing around a bit. So what do you say, would you suck my dick?"
I bet there will be surprisingly lot of people sucking off each others dicks for a lesbian sex party.
The weird and frustrating thing is that even in a case like that people would still have to call them "she/her", otherwise it would be hate speech and they would be outed as a transphobe. Like really, a bunch of men in dresses wave their dicks and ask women to join them to have "lesbian sex" and the thing you have to be the most careful about is to remember to call them she. In this exact case if it's really true that this GLLTY person is just "sometimes trans" it's even more baffling to insist on using the word she after something like this happens.
I'm ok with calling trans people whatever they like but when someone with a dick asks a woman to have lesbian sex with him/her/zer, no, you are not looking for lesbian sex, you are looking for hetero sex and you are trying to cheat and deceive your way to that and you are abusing LGBT community and culture to get what you want, and you don't get to have the world to play this scheme with you by forcing everyone to insist you are a lesbian girl. I get fetishes and fantasies, and they are all ok, but a line has to be drawn at some point.
It's ironic that a case like this can't be seen as part of toxic masculinity. People call out men for waaaay smaller cons to get women and say it's part of toxic masculinity and rape culture, but if someone wears a dress and insists he is she, they can't count it part of that anymore. Instead it's even worse if you would count that in.
