Interesting question. About half the time I think they are "fake", I'll just get the vibe that the whole production serves some end for them and I just roll my eyes the same way I do when I see a kid who works at McDonalds wearing a rolex watch.
The other half of the time I think they really believe in what they are doing and I'm just baffled becasue I just don't get it. I just don't understand that sort of devotion or super spirituality if you will.
