I think you've misread my comment.
I'm not interested in their description of transphobia, transphobia as a term and idea has been so thoroughly overused as to be utterly meaningless.
What I'm concerned by is the suggestion that anyone has to 'refuse' to have sex with someone.
It's assuming a blanket assumption that (women, particularly) have a default agreement to sex that requires a woman to state 'no' - and the wording implies furthermore that she is required to explain her reasons.
I've discussed this before on this board, and I know some people struggle with ideas surrounding consent.
Consent isn't about someone saying 'no'. Consent requires an enthusiastic, fully informed 'yes'. Women are not service sexbots that have to explain why they don't want to have sex with people.
Women are perfectly capable of making their own decisions of with whom, and when, and in what circumstances they are interested in having sex, without anyone judging their motivations or questioning their reasoning.
Nobody should assume that a woman is open to sex with everyone and has to say 'no'. Everyone should assume that everyone else is NOT interested in sex with them unless it's made explicitly clear they are.
Saying 'I am a lesbian, and attracted to women' is a sexual orientation or preference. A positive choice.
Consent is not and should never be defined by the groups a woman isn't attracted to.
Nobody needs to make a list of 'who they won't have sex with'. It's absurd to even suggest it.
