I, on the other hand, am most familiar with the Brethren in Christ and the like, which are distinctly less radical and extremist, even if they are still somewhat fundamentalist. I'm also familiar to some notably lesser extent with a number of other significantly varying branches of Christianity and a few other religions.
Ugh. It's not as bad for the BIC, but yeah, it's still pretty much brainwashing. I, at least, was raised in a congregation where the pastors usually preferred a somewhat more intellectual and good morals approach, regardless, rather than directly embracing YEC (some of the other congregations embraced it more, though), the Omphalos hypothesis, and general ignorance. Of course, I also went to a public school that only specifically taught about religion in a somewhat secular way, even if students were not especially restricted from gathering to practice their religions. It still took a couple years to largely undo what brainwashing had been done to me, though, and the social consequences for me were quite mild, really, as far as I'm concerned (but then, I'm also mostly a hermit by nature).
