…a separate society within American society, where the kids are home-schooled and kept separate from other children so they can be thoroughly brainwashed.

There are Muslims who do this as well. The kids I’ve met are generally very polite, well-behaved, and score higher than normal on standardized tests (in places where they’re required to take them), however they’re usually also extremely naive and painfully socially awkward when required to deal with peers who’ve been educated in public (or regular private) schools. They simply aren’t equipped to deal with the secular world outside their homes and/or immediate community. It can be a real problem when they reach reach college age and want to pursue higher education.
