Oh yeah, extreme creepy weirdness that often goes all the way into sexual harassment, sexual abuse, grooming or worse... just absolutely endemic with youth group pastors in the US.

But its hugely underreported, partially because, well, uh, religious indoctrination just is a form of grooming in and of itself... and then yeah, as you've described more thoroughly, its basically a perfect storm of every factor you'd need to encourage and then supress reporting of sexual abuse.

But, of course, this kind of thing is so socially normalized that... religious people rarely stop and just think about it.
