You're right, though I know that Jehovah's Witnesses do stick to all of that.The question has to be therefore why is 18.22 with its prohibition of homosexual practise so often referred to these days and not the others?
Do modern churches devote such time and energy condemning heterosexual sin? Thought not.
The righteous position is not to condemn homosexual behaviour by itself but all sexual misbehaviour outside of the sanctity of marriage. As I have said above no church will get many takers for that one in this day and age.
