I mean, you're preaching to the choir here: I'm a nontheist and a lesbian. I did used to be a Christian, but I feel my responses are more terse on this because it feels like speaking for someone else, and especially when I'm speaking about things I don't agree with.
I'm try to understand the logic behind the idea. Thought you may have looked into it before.
I've now had a look into attaching the city of Sodom to homosexual sex.
It comes from the word "Know" (Hebrew - Yada)
So the men of Sodom wanted to "know" the men in Lots house.
And they called unto Lot, and said unto him, Where are the men which came in to thee this night? bring them out unto us, that we may
know them. Genesis 19:5
And the daughters of Lot have not "known" man:
Behold now, I have two daughters which have not
known man; let me, I pray you, bring them out unto you, and do ye to them as is good in your eyes: only unto these men do nothing; for therefore came they under the shadow of my roof. Genesis 19:8
And Adam "knew" Eve:
And Adam
knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the Lord.
So to know someone means to have sex with them.
So when the men of Sodom wanted to "know" the men in Lots house, that means they wanted to have anal sex with them.
From this interpretation of the story of Sodom, we now have the word Sodomy which means anal sex.
I guess that can make sense if disregarding all the hundreds of other bible verses that have the word "know".
I wonder if true Christian men really "know" Jesus.
