It's not something I would personally do, or even wave a flag for. Let people make their own decisions. Christians, Jews, Muslims, etc. worry too much about what homosexuals are doing, when they should really be worrying about other things.
It's not my place to tell somebody what they can and can't do. I don't support it, but I cannot look down on somebody for what they do. I am a Christian, but I also am a human. Sure, most Christians like to single out the gays for what they do, but that's just not the Christian way. Many will sit and judge the gays, and they will turn around and lie, they'll be a glutton, they'll cheat, they'll even turn their back on the needy. All of those things are bad, but because being gay is so taboo to these people, they single it out, because it's something they don't personally do.
I've had many gay friends growing up, and I love them just the same. It is not my place to judge them.
