Well when witnessing today's efforts of gay movement fighting for marriage and for a right to raise kids and all sorts of other stuff which has nothing to do with a fight for human rights anymore but rather with a subconscious lack of self esteem of gay people who want to look like str8 in all aspects - then yes I am ashamed to be gay.
Thinking of what it means to be gay for my identity - then I'm of course not ashamed to be gay at all.
But the fight was for equality, equality in basic rights, equality in work, equality in the eyes of the law, and now leading to equality in marriage. There is nothing wrong in being considered "normal", that's what the whole thing was about, it certainly wasn't about remaining different or special, just exactly equal with everyone else.
That's what all minorities of every description ever want.
It's like a soldier after the war is won still wanting to fight. Not that I mean anyone can be complacent about anything, but gay rights in the West , and improving slowly in other places, are beyond probably what was ever dreamed in those first marches.
Equality, I believe, was always the goal, not seperation! It's certainly not a lack of self esteem. Surely the opportunity of being able to live a life like the rest of the main population without any stigma is what everybody wants
