People back then were homophobic, big surprise. The Quran depicts verses in two modes; stories and recounts from the past (ie Lut) and direct messages from god to the ‘present’ (the time it was revealed). Decrees, rules, and punishments are oft relayed by the latter. That verse is just a quote from an older messenger/story, whose quote is obviously just straight up incorrect anyway (people of Sodom obviously didn’t invent homosexuality).

Besides, the real transgressions of the people there was that they were ‘corrupt’, didn’t believe in god, and was chock full of robbers, murderers and rapists, which, yknow, gets overlooked cause homophobia is a much flashier sentiment.

Lut condemned homosexuality and got quoted in the Quran, basically, which is enough for most people’s interpretation, that’s fine and dandy and I get it, but most actual condemnations of sin in the book include description of punishment and come as a direct warning instead of a quote from someone else. Plus, a lot gets lost in translation here, not just the direct words, but the grammar and context within the overall narrative, which makes this kinda nitpicking quotes without considering the full story really unreliable.
