It’s a little worse than that. They encourage dangerous and deadly behavior because they don’t care if people die or get hurt. They only care that they themselves appear virtuous by being on the “right side” of every issue.
That’s something people do because they are already depraved.
Think of Romans 1:18-32 as describing a perticularly dangerous on ramp to the broad way that leads to destruction (which would be refusing to retain the knowledge of the Lord).
Championing homosexuality is society is like a particularly notorious road sign to tell people who aren’t depraved something about those displaying the trait. But it turns out it isn’t the only or even the last possible such sign, and what was comedy and biting satire decades ago (including advocating for transgenderism) is just one thing people are doing for whom the sign listed in Romans 1 is simply passé and quaint.
On a more secular level have you ever seen Evan Sayet’s presentation on how so-called Liberals think? It’s not short but it’s worthwhile.
