I would say this definitely applies to specific sects of certain religions. Probably not to all. A number of sects of Christianity count. The idea that everyone is evil and deserves hell until repenting is a pretty twisted worldview. The shit they put on girls and women is deplorable. The sects share in common several techniques used by cults. So basically they are cults. Teaching kids to reject people different from them is vile.

I’m not convinced it applies to all religions, however.
