yeah lusting for or having sex outside of marriage is considered a sin despite whether it's homosexual or heterosexual. I think the reason it's not met with as much backlash as homosexuality in the Christian square is bc the culture has just become so used to sex out of wedlock that nobody really is surprised by it anymore.
Tbh that probably wasn't a good choice, bc then came porn, and then it just went wild. Now you have people arguing pedophilia is okay. Did you know John Mooney, one of the LGBTQ community's founding fathers, was not only a pedophile, but he would "care" for children and test sex change operations on them with or without their or their parents' consent, and would have them play erotic games and do wildly inappropriate things with each other, while he invited his friends to "enjoy the show"?
I've been trying to tell people this for a while, but at first the argument was just "let us be gay", but that is not the final culture shift intended now, nor was it ever intended to be. The plan was always to make more things okay, one thing at a time, and pedophilia is one of the things on the list. That doesn't mean the whole community supports pedophilia (most don't, and I'm glad to agree with them on that), but what it does mean is that the people who pushed this always had that in the plans.
