I agree with you Rick. I'm involved right now in a campaign to defeat an anti-gay initiative and the most discouragement I get is from gay people. 99% of the straight people I've approached about the amendment immediately came out strongly in opposition, grabbed my literature and put the buttons on their shirts.
But some of the gay people I approached about it refused to take the literature, some "explained" to me that "these issues are very controversial, you see Zerbie, don't expect support" and some flatly waved me off saying, "Oh honey, I don't care about THAT."
My passion for LGBT activism has cost me a few friendships with people who were uncomfortable it. One was straight, the others were all gay friends who pulled away when I got "political."
Ten years ago when I first became involved in LGBT activism, it was an openly gay person who took me aside and lectured me to get out, I quote, "Don't ruin your life trying to help people like me. We aren't worth it."
