You don't see it because you aren't looking. As for the whole "old testament" thing, I've suggested to some anti-gay bigots that we should be out stoning to death people who touch leather, work on Saturday, eat shellfish and such, and they use that (completely fucking stupid) line "but that's in the old testament, and we don't follow that anymore" only to turn around and use the command in Leviticus to support their anti-gay bigotry.
THE problem is, there's too many idiots who only listen to what their preacher says, and can't seem to find time to actually read the Bible. That's why their version of "God" seems to hate exactly who they hate. The other problem is, religious people ignoring the plank in their own eye, while thinking their shit don't stink and throwing stones at other people.... which is EXACTLY the problem with a lot of posters in the thread.
Actually, the new testament speaks out against homosexuality too. But it doesn't advocate violence against homosexuals.
