From earlier on in the tweets:
AR - your inclusiveness does not include people who believe in same sex attraction
R - I believe that denying trans woman is a woman, trans man is a man is transphobic.
And denying that homosexual people have sex based attraction regardless of other people's subjective sense of gender and choice of identity is homophobic.
So let's get to the brass tacks here of why denying trans people is a problem, but denying homosexual people is fine? Because this is just plain saying trans people are more important and trump everyone else's sexuality and preferences and rights.
