Briefly on the topic of religious tolerance - I agree with your estimation of Scientology...and especially if all this Xenu crap is really doctrine I think they're nuts, unbalanced, and probably a bit dangerous. But I think the benefits of the principle of religious tolerance as currently practiced in the U.S. may outweigh the costs of having a bunch of looney tunes around who believe that the souls of 178,000,000,000 murdered extraterrestrials are stuck to my psyche (and everyone else's) like peanut butter.
It's a subject I really ought to put more thought into, but I know of two historical cases of the introduction of religious tolerance - back in ancient Persia with Cyrus, and the founding of the U.S. - and in both cases, religious tolerance seems to have been a good experiment for those who tried it.
I'm leaning more towards actual atheism - in the formal sense, which I would regard as a belief system in its own right - every day - but when it comes down to it, I cannot prove that the Christians are wrong about the resurrection of Christ. I can point out the complete lack of reliable evidence of resurrection until I'm blue in the face, but I have no direct experience or evidence in this regard, and I think me trying to say to them "I think it's harmful for you to believe in this stuff" is just as bad as them saying to me "You're a sinner if you don't accept Jesus into your life as Lord and Savior." It's an example of trying to force someone to believe something, and ultimately I just have no control over that. Besides which - though I'm more and more atheist-leaning - there are things in my life and ways I've felt that defy all sorts of conventional explanation, and I'm not about to dismiss those out of hand, which I think is just as dangerous as believing in things out of hand. I don't really have time to get into all of those right now, but there have been some, such as the 2004 tsunami, when I dreamed about rushing waves of water at pretty much the exact time it was happening on the other side of the frickin' world. THAT one especially bothers me as someone who's extremely skeptical of parapsychic phenomena, but I didn't make it up.
I think the idea of religious tolerance may actually help to foster creativity by allowing people of a wide variety of beliefs the freedom to explore these beliefs. I would be grateful of more historical examples on this subject if anyone has them.
