Yeah, I heard about that and it seemed super-strange. I mean, lesbian or not, I have the right to have sex with whoever I want, not the other way round, no? Forcing someone to have sex is sexual harassment and should be punished, not supported/endorsed by anyone.
I think what OP means is that if lesbians refuse to have sex with trans men (male-to-female) who declare themselves as women, they (the lesbians) are marked as transphobes. As contorted as it is.
