1. "Abomination" is broad term used very freely:
Leviticus 11:11 And since you are to regard them as unclean, you ... [TABLE=border: 0, cellpadding: 0, cellspacing: 0]

They may not be used for food, and their dead bodies are disgusting to you.
Leviticus 7:18 If any meat of the fellowship offering is eaten on ... [TABLE=border: 0, cellpadding: 0, cellspacing: 0]

[TD]... But whatsoever hath not fins and scales, of those things that move

There are six things which the LORD hates, Yes, seven which are an abomination to Him:
1 Haughty eyes,
2 a lying tongue,
3 And hands that shed innocent blood,
4 A heart that devises wicked plans,
5 Feet that run rapidly to evil,
6 A false witness who utters lies,
7 And one who spreads strife among brothers.
Sodom was guilty of many Abominations (note that any "sex crimes" do not even make the list above or below):
48“As I live,” declares the Lord GOD, “Sodom, your sister and her daughters have not done as you and your daughters have done. 49“Behold, this was the guilt of your sister Sodom: she and her daughters had arrogance, abundant food and careless ease, but she did not help the poor and needy. 50“Thus they were haughty and committed abominations before Me. Therefore I removed them when I saw it. 51“Furthermore, Samaria did not commit half of your sins, for you have multiplied your abominations more than they. Thus you have made your sisters appear righteous by all your abominations which you have committed.
But God promises to RESTORE Sodom to it's former state becasue Jerusalem was so much worse and did not embrace it's family and relatives and did not offer housing to strangers.
And issue #2:
Legally only a man and woman could live in the same house according to local customs.
All other forms of living arrangements were considered abominations.
So when scripture is referring to other types of couples as abominations, it is referring to people who sleep around and
are promiscuous or having orgies or sleeping with both men and women freely and often.
The reason this is obvious ais that these types of activities are obvious and harmful to society. Having multiple partners
and "free love" with multiple people is harmful to all of society. Scripture is not referring to ANY committed relationships as bad.
How do I know this? Becasue sex between committed partners is completely invisible, I mean 100% invisible to society.
Sex done properly is never a matter of public record. It never leaves behind any abandoned partners, stories, or diseases.
It is 100% invisible. If you look closely at these judgmental passages, they are referring to abhorrent behavior and promiscuity.
They are not referring to gender preferences though gays do get noted
for those having poor and visible behavior.
