I am no religious scholar but I think its unfair to single out just those religions. I think most religions accept this type of nasty behaviour as it was the norm when they were created.
Yes, it is. Also the cult in which River Phoenix, who claimed that he lost his virginity at the age of four, was raised. He said that "they're ruining people's lives."
Also this clip reminds me of all the creepy cult-like worship-singing scenes in The Trial of Billy Jack (which is pretty much the entire three hours of the film).
