Concerning the freedom of religion....
Mormons had to conform, that multiple wife thing was not catching on.
Branch dividians got cooked for their indescetions, I think they had a sex thing too.
Moonies went international, not sure how that played in USA.
Chuckie Mansons' group pretty well peed everyone off, but criminal activities made religious activity a moot point.
KKK has a religious aspect, a strong one, but they also have criminal activities,perhaps they are not primarily religious and religion is a secondary thing.
I am just throwing those up there as an example[s]. My question is: what is the threshold that deems a religion a hostile force against the USA and not worthy of freedom of religion protection/
Yes, my curiosity is aimed at islam if you wonder.
Not all legal, it maybe public opinion, numeric reality, and other things. But the primary point of my confusion is the legal aspect.
