My main mantra is "to each their own" even if I don't necessarily agree with it. What I know of Scientology leads me to believe it's a bunch of crap but whatever floats your boat...

... The biggest probably that I have is that it is called a "religion". It is not a religion. It is not based on or focuses on a God of any sort (God, Allah, etc.). It was "created" by a science fiction author, for God's sake! Therefore, in my eyes, it's more of a new age cult or a social gathering of people than a religion. When people refer to it as that (a religion) is the only time I get upset. It is decidedly NOT.
