First off there are two passages in the O.T. that directly prescribe the death penalty for male homosexuality, not one like you said.
Second neither one of which contain the Hebrew word for “boy”. Both use the words to describe a man.
Third even if they somehow meant to write boy but didn’t in context it would still work out to mean man.
Fourth the rest of the bible is completely consistent on this which is almost shocking given that it is consistent on so little. From Leviticus all the way to Paul, we got about a thousand years of different writers all saying the same thing on this one issue.
Fifth even texts that didn’t make it it in the Bible (at least directly) like Enoth still go after it.
Sixth the oldest commentaries all agree what the rules were about this.
The abhramic faiths are on the text level homophobic. No amount of apologetics, or crappy translations, or recontextual work will change what they contain. When people or religions tell you what they are about believe them. And stop following these shit tier religions.
