I guess I should assume you misunderstand the quote you provided. "With such a blind and naïve moralising approach, the whole vast storehouse of spiritual culture is devastated and its treasures detonated..."
So you're anti-LGBTQ. You're kinda, sorta referencing the Bible in a simplistic, moralizing way. You're condemning people to hell, as if it's your call. And you're asking me to explain you to you. 🤷♂️
For me, the story of Sodom is about inhospitality, not homosexuality.
Ezekiel 16:49-50 - "Now this was the sin of your sister Sodom: She and her daughters were arrogant, overfed and unconcerned; they did not help the poor and needy."
Any doubts are clarified from the New Testament and the example of Jesus, how he walked in this world and treated others.
