Ask them where the term “sodomy” comes from.
They will say that the Genesis account of Sodom was about the horribleness of the attempted rape (of the angels), not homosexuality.
Problem is, is that before the angels even went into Sodom, Genesis chapter 13 says that the men of Sodom were “exceedingly wicked.”
And Jeremiah said that the people of Sodom were prideful, had no compassion for others BUT also mentions that they committed abomination - homosexuality.
Jude points out in the Book of Jude that it was the ever constant homosexuality and lust among the homosexuals (rampant even in the streets) that caused God to destroy the city.
