It's sad how some of you think it's okay to ban a religion, no matter how wacky it may be. It's not as if Scientologists are out to harm people.
If anything, I welcome crackpot religions. It makes it easier to weed out the morons with labels like "Scientologist". When someone tells you they're a Scientologist, it's a huge red flag that immediately instructs you to cease communication with said person and quickly walk in the other direction.
