Homosexuality is a particular sort of very unnatural behavior. It belongs in the category of a sow eating her piglets, or Tom cats killing kittens. It is a blatant rejection of the natural order of things. It is virulently abnormal.
In the Bible, several cities are utterly destroyed as a result of Homosexuality. I can only regard this as a measure of God's vehemence on the subject.
Not nearly as many as were destroyed for worshiping false gods.
Then why is San Fransicko still around?
