Show me a channeler, medium, professional psychic, etc and I’ll show you a liar and a fraud.
A hand full of them are just delusional. The vast majority of them are con artist. NONE of them are legitimate.
Believing in a deity is not anymore rational than believing in channeling. One could say, using some people’s logic on this thread, that Priests, nuns, etc are all con artists. I would not agree with them, but it is funny what people decide to believe or accept and what they see as absolutely nuts. Just my observation:)
