The issue to me, I’m not opposed to that as much as I’m opposed to redefinition of a 5,000 year definition of marriage. I’m opposed to having a brother and sister being together and calling that marriage. I’m opposed to an older guy marrying a child and calling that marriage. I’m opposed to one guy having multiple wives and calling that marriage.

BELIEFNET: Do you think those are equivalent to gays getting married?

Oh , I do. For 5,000 years, marriage has been defined by every single culture and every single religion – this is not a Christian issue. Buddhist, Muslims, Jews – historically, marriage is a man and a woman. And the reason I supported Proposition 8, is really a free speech issue. Because first the court overrode the will of the people, but second there were all kinds of threats that if that did not pass then any pastor could be considered doing hate speech if he shared his views that he didn’t think homosexuality was the most natural way for relationships, and that would be hate speech. We should have freedom of speech, ok? And you should be able to have freedom of speech to make your position and I should be able to have freedom of speech to make my position, and can’t we do this in a civil way.

I am truly insulted, offended and disgusted by his comment. I feel that a person that would compare two consenting adults as pedophiles (force) and those that practice incest is an UNEDUCATED IDIOT!

I am truly disappointed in Obama for choosing Warren for his inauguration.

I understand when Christians state homosexuality is an Abomination in the eyes of God, but when you state what he stated, there are no other decent words that I can state other than disgust.

Rick Warren has these strikes against him: He compared “gay marriage to incest, pedophilia and polygamy and repeated the inaccurate charge that without Prop 8, conservative preachers could be prosecuted for hate crimes. He described ’social gospel’ Christians of the 20th century as closet Marxists.”
