He has spent years working against the best interests of the queer community. He's still saying that he's not one of us, and that it would be wrong if he were. No sympathy here.

I would feel sympathy for, say, a closeted minister,outed by an ex-lover, who had focused his preaching on urging his congregation to follow the example of Jesus, and his political activity on something I am sympathetic to. But this man has gotten rich urging strangers to hate and oppress me. Why should I support him?

Christians can offer all the support they feel appropriate.
