Looks like Scripture defined our fellow Americans centuries and centuries ago.
Leviticus 18 and 20
Chapters 18 and 20 of Leviticus, which form part of the Holiness code, contain the following verses:
Thou shalt not lie with mankind, as with womankind: it is an abomination.[2](Leviticus 18:22 KJV)
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.[3](Leviticus 20:13 KJV)
The two verses have traditionally been interpreted by fundamentalist Christians as blanket prohibitions against homosexual acts.[citation needed]
Traditional Jewish sources view these verses as prohibitions against anal sex between males only and have a different approach to female sexual activity. [4]
