Leviticus 20:13: If a man also lie with mankind, as he lieth with a woman, both of them have committed an abomination: they shall surely be put to death; their blood shall be upon them.
This is not up to interpretation. This is black on white: kill homosexuals (and for some reason no lesbians). 'Up to interpretation' is made up by religious people for the truly horrible things that are said in the bible. And yes there are way more horrible things described in the bible. You either believe everything or nothing as the bible is the word of god.
