It is hard to put yourself in other's people state of mind, and to reason that it's because they must be idiots is not really the proper way to go. I don't have any advice to give on religion, if it's not your thing fine, but painting people with too broad a brush may lead to misuderstandings, conflicting exchanges, and ultimately animosity for no good reason.

So my only point is: you probably have something that you hold dear to your heart and you would not liked to be judged or criticized for that, in some ways it's not even anyone's business but yours. Religion, spirituality, or weird new age practices are the same for a lot of people, and it doesn't presuppose that any of this is good or bad, it just is, and mounting a file against all of that at once is bound to be fruitless, and hurtful for the people involved.
