So gays and transpeople do not share anything in common because a prominent gay politician did something that hurt the trans community? That means ALL gays and transpeople have nothing significant in common? What about the gays and trans people that aren't involved in politics? Both have to come out to their parents, both get beaten up, both have narrow-minded interpretations of religion thrown at them.
(trying to stay on subject here) one thing I think that gays, TS's, and Cd's all have in common is that we are ALL persecuted for gender transgressions. Cd's look like the wrong gender. Ts's identify as the wrong gender. Gays love the wrong gender. So at the very least Donna, I would hope they'd feel some sort of connection based on a mutual desire for tolerance and being non-judgemental.
