1. Alternative theories state that demons just fear sincere faith in anything. If you apply the kind of rigor you're using, sage and chanting sutras also drive out demons. Once again, this doesn't prove anything.The article speculates that it could be mass hysteria but it does not make any conclusions. And it is theorized that the symptoms caused in Mattoon was caused by toxic waste from industrial plants.
The fact that demons fear holy water and priests can drive out demons in the name of Christ indicates that Catholicism is the true religion. Anyway, you said that your Catholic because you believe it is supported by evidence. If you don't believe that my evidence is sufficient, perhaps you can share the evidence that makes you believe, so that people can see the evidence and convert.
2. I never said that; I said that, going by reason, Buddhism is the "true" faith, because Buddhist metaphysics claim that extraordinary physical abilities are unlock on the path to enlightenment, and said extraordinary physical abilities (such as the ability to regulate one's heart rate, body temperature, and autonomic reactions consciously) have been scientifically documented in Buddhist monks. My reasons for being Catholic are because of family tradition, and because of reasons which are very personal to me and which I am not going to share on an internet forum.
In addition, I don't believe in the kind of tawdry side-show evangelism you practice; it cheapens the faith.
