It's becoming rather sad, actually. Watching the man self-destruct mentally; seeing it affecting his career. Mind you, while it may be sad, I have little sympathy. We choose our own paths, and few things are more wrong-headed and doomed than assuming one's own infallibility and importance.

Oh, my. I just had an interesting thought. You can't quit Scientology - not really. So, what if this extremely public, crashingly messy past two years of bringing Scientology into the limelight in such unflattering, "why'd we pick this guy to represent us, again?" fashion is a way to distance himself from them, by their eventual choice? What better way to set up a future 'rehab' time away, than to crash and burn?

Of course, this is simply a passing fancy. Hell, it was his goofy fellow Scientologist sister who took over the reins of his management and let him off the leash a couple years back, encouraging all the creepy behavior and flappingly spastic interviews. Up until then, his keepers had kept him well behaved and seemingly "normal."

Actually, those definitions are accurate, if not entirely defined, and by no means complete. The Rolling Stone article on Scientology is perhaps the best, most comprehensive one I've ever read.
