@Bloomfer Why? Easy! This is taken from a Reddit post, I believe, and discussed on Twitter.
It’s verboten over at Reddit to say you’re not attracted to TIMs otherwise you get banned and only TRAs or trans are left to tell the girl she has to conform. Just look at the sub Real Lesbians: the only lesbians there are girls like this who have learned to accept penis which is conversion therapy, the majority of users are TIMs.
As for Twitter, I think users there are still learning what they can and what they cannot say to avoid bans. And lesbians are the last worries on a lot fo straight people’s minds.
