Go get 'em. Seriously. I came to this same conclusion more or less about 10 years ago. I never studied philosophy beyond a frosh class in college and was never religious. I like to converse with people about religion and it generally boils down to "What's the point?" No one knows, or will ever know. Most religious beliefs and arguments are about what's right and what's wrong. Fine, let's debate that without all of the supernatural mumbo-jumbo in the way. (BTW, if you want to have a good debate, never offer as proof "Because the Bible says so.")
As far as the article, once again, what's the point? If he wants to molest children, he should be locked away, no matter what the cause. The judges can determine if it's prison or a hospital. I'm glad that he was treated and was able to be released. I have sympathy for his plight and everyone else in this thread who had experience with brain tumors. But I still don't want them around me or my family if they're violent.
BTW, have any references that I can peruse along these lines? I'm always interested in exploring this line of thought more.
