The "Gay Bigendered Tranny Whatever" lobby really sets themselves back with crap like this. The gay men I know just laugh at the tranny-types (and even NAMBLA), which just sets their resentment level higher.
They have their eggs in one political basket, know it, and just have to ride it out with extremism.
Which is a shame, because there are some decent Log Cabins who sit square with the rest of us.
