So, this person quits. Sounds like a bit of an ideologue who didn't get carte blanche, I think. Gave the usual spiel which makes it clear they are only about the T.
"I don’t believe that they understand LGBT people, particularly trans people."
I don't think their remit was only to be the Trans Adviser. Have they nothing to say about equality in relation to any other group of people? Disability, race, belief, SEX, childbirth and maternity, etc. etc. They talk as if anyone who isn't a trans ideology is a right wing evangelical; usual attempts to smear there. Oddly enough, many regard the trans ideology as rather anti-gay when it puts lesbians under pressure to regard their sexuality as not being related to sex. That is why alternative LGB organisations are having to be set up in so many countries. A big cuckoo has taken over their nest.
I'd imagine it is good riddance and don't let the door hit your bum on the way out. They don't seem to have any interest in equality per se; never mind balancing different rights. Only about entrenching this single ideology.
Wouldn't it be wonderful to have an Equality Adviser who took a broader view than Trans activism?
