hmm, I dont think the bible meant to littearly kill them...
Leviticus 20:13: "If there is a man who lies with a male as those who lie with a woman, both of them have committed a detestable act. They shall surely be put to death
I think this means that they wont go into heaven, homosexuality is a sin, and sinners can not go to heaven unless they repent of thier sins...
I think he was wrong for saying what he did, I am a christian, and I do belive its a sin, but I have homosexual friends, who are honestly great people and I want them to be just as happy as I am... Overall every individual has the right to make thier own choices, in fact God specifically says that we have our own free will.
