Actually Religion is mostly about mind control. It tell you what to think and when to think it.
Scientology is worse because it's members will actually gang up on you, kill your pets and possibly kill you. They will also sue you (or try) into oblivion.
And the thing is... they'll get away with it because they have enough money to buy the cops off.
