COME TO THE DARK SIDE, SUZANNE! WE HAVE COOKIES!
Mmm... cookies.
Okay, seriousness about Scientology. Honestly, I have no problems with people believing whatever they want to believe so long as it doesn't cause harm to other people. If it gives someone a warm, squishy feeling if they give a massive amount of their money to assure that Xenu doesn't prevail over the universe... yay for them.
The aspect of Scientology (and any other fringe 'religion', for that matter) that I don't understand is the pathological need to be considered legitimate. If the powers that be within Scientology just let the jokes and naysayers' comments roll off of them, I don't think the entire world would be so fixed on making a big deal about it. Of course there would be those who choose to make a big deal, but I doubt it would be at quite the epic proportions it is currently.
I hope that made sense. It's about eight kerjillion degrees outside and my brain is a little fried.
