The thing is, no matter what you do, the majority of people seem to NEED something like a religion. They do not want to think for themselves, they want to belong to a large group and/or they want some kind of outside confirmation that they are in some way "better" than others. So no matter if the next big thing is going to stay Monotheism, or become Scientology or whatever other trip, there is going to be something resembling one and it will probably be stupid in the eyes of non-believers.
Objectively speaking, I must acknowledge Scientology as a faith. It has sincere adherents.
However, I view Scientology as being just barely a religion. It was clearly founded with fraudulent premises. Its beliefs are internally inconsistent. Its approach as a mystery religion is clearly designed to make money and exert power.
The Church of Scientology is a repellent organization that is somewhere between a cult and a crime syndicate. And by spreading absurd ideas about psychiatry, they do real harm by causing people to not get the treatment they need while undercutting valid criticisms of psychiatry from Ssasz to Foucault.
