The GLBT community face a lot of stereotypes--Openly making out gays (heteros do this A LOT, by the way), perverted, pushy, flashy, et cetera.
I have a lot of gay friends. They never flaunt it. They respect heterosexuals and never push anything on them. But what bothers them the most, from what I can see, is how religion in constantly thrown into the argument. If it's not right to flaunt Wicca or another religion, why do the Christians flaunt and push their religion on other people? It doesn't happen all the time, but it does happen.
"Marriage" is viewed as sacred. But I honestly don't think it's sacred if people like Kim Kardashian can marry and divorce one month later. But giving the same rights to the GLBT community and calling it a different name is no better. It still makes it different.
Everyone deserves to be happy. If it hurts someone else or yourself, then there is a problem. GLBT marriage doesn't hurt anyone. And if there is an issue regarding religion, I think that it's between that couple and God--not a nosy neighbor, religious zealot, or anyone else.
As a side note--I once argued with someone who equated homosexuality to alcoholism. I still don't know how to feel about that . . .
