Why are their pastors driving lambos

Have you ever talked with fundamentalist? It's not only plausible, but those adults have probably done the same thing while actually being serious about the preaching part in the concert

Yes.

Religious fanatics are that gullible, they do after all believe in really shittily written fairytales as if they're real.

Yes! I went to an evangelical church run private school. They had the brilliant idea to send good "strong Christian" students to raves and parties to narc on their classmates that attended said raves and parties. I wish I was making that up.

Depends on the town. Some of the ones in the Bible Belt? Absolutely possible. In others it's completely possible they knew the kids were lying and decided it was fun to play along and get them to a concert.

I'd be astounded if they didn't.
