> P.S. in the first para by "normal" I mean that if you ask many random religious people of age 30+ most of them would consider that behavior normal.

I was raised in a religious household, am 30+, and don't consider coerced prayer of the type that seems to be described [0] normal (in fact, I find coerced prayer theologically unsound.)

OTOH, I wouldn't be surprised to find it fairly common.

[0] An expectation of respectful silence while someone else leads prayer, or an offer without obligation to lead group prayer, certainly. But coerced prayer is another thing altogether.
