the only weird thing is that you don't see the difference.
scientology is not a religion, and in most civilized countries it is not recognized as one.
and in my opinion, it's not even a cult, there is nothing spiritual about it. it's front is a therapy movement based on bogus science, but it's methods are borderline legal and very close to organized crime, people are getting harrassed, blackmailed, intimidated and threatened on a daily basis. I am not too fond of christianity and islam either, they sure had their fair share of cruelty done in their names, but I recognize and respect that most christians and muslims live a peaceful life under spiritual guidance of their religion.
that's not the case with scientology, it's all about profit and brainwashing there.
