It actually was forbidding men raping other men as a show of dominance, basically it was denoting it as a type of war crime, it’s only modern translation and only very recent translation that’s decided suddenly it’s about gay men, which it l never was. it’s unclear if anyone even accepted the concept of gay men in those days, but they did have 6-9 genders, so perhaps to them a gay man fit a category they didn’t bother condemning. it certainly wasn’t important enough for Jesus to bring it up. an he mentions 5 genders and doesn’t say any of them are sinful.
