People who say, “Sodom and Gomorrah were condemned, not for homosexual acts, but for lack of hospitality” really need to retire that ridiculous meme. The biblical text is pretty obvious. When the angels come to visit Lot in Sodom, he takes them in. “But before they lay down, the men of the city, the men of Sodom, both young and old, all the people to the last man, surrounded the house; and they called to Lot, “Where are the men who came to you tonight? Bring them out to us, that we may know them.”
“Know” is the Hebraism for sexual intercourse. The story crackles with the menace of gay rape. The mob (whom the writer repeatedly emphasizes were men) “pressed hard against *the man* Lot”.
As Scott Hahn points out, the threat of homosexual rape is a particularly acute form of “inhospitality”.
