I think it's an aesthetic thing for a lot of people. Especially those into electronic music. Some people just can't stand the "hippie edge", and find it to be outright bad taste. I'm sort of on the fence about it. My interests in spirituality and metaphysics makes me receptive to the themes and general grandeur of the genre, but only as part of my own subjective interpretation, which honestly be couldn't further away from the cuddly new age, girls dressed like birds, hippie-decadence of the Trance scene.
