I'm very careful not to stray into religious discussions on stock message boards, so when I use the word "belief" I don't mean it in that way. Randi might be including that category.
You're correct, the sheer depth of the ignorance and self-delusion is breathtaking. I can only repeat the quote that I sent to Janice:
“You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe." -Carl Sagan
