Ron Paul IS NOT in support of gay marriage. He just thinks the federal government should not decide it. There is a major difference there.
And yeah, you guys should seriously learn to not bash Christians. Some Christians make bad decisions just like other people.
Ron Paul answered, "Sure" to the question asked of him on an ABC interview: "Should gays be allowed to marry?".

Paul himself may disagree with homosexuality and gay marriage, but he is absolutely opposed to a federal ban on it. The candidates that Evangelicals support (such as Huckabee) aren't able to make the distinction between religious values and political ideologies. Many "conservative" candidates wish to outlaw gay marriage, and define marriage on the federal level as the union between a man and a woman. Ron Paul has the sense to not ever support such a thing.
EDIT: I should say that none of my comments are meant to be personal attacks - they are my opinion, and the fact that we have such wide-ranging individuals all supporting one candidate just speaks towards Ron Paul's undeniable strength as an ideologically-powerful candidate.
