Remember everyone, it's a sin to be left-handed.
Nobody said God wanted everyone to be gay. This makes no sense.
In the same passage, the Bible also says that among homosexual sex, shaving your beard, eating shellfish, and wearing clothes from two different kinds of fabric is a sin. If you wanna believe the Leviticus rules are legit, ok, but you don't get to pick and choose which of "God's Laws" you want to follow. If this is you basis for saying gay marriage is wrong, then I hope you haven't picked up a razor recently. After all,
why can't I own a Canadian?
This. Many people who call themselves Christians are very happy to condemn other people, even though that's the exact opposite of what Jesus was trying to teach. "Judge not, lest you be judged" anyone? Christianity is supposed to be about love, not hate. Didn't Jesus preach that if you considered yourself better than others that you were just as bad as the people you condemn? That doesn't sound like many modern Christians to me.
