Religion just happens to be ONE of them that through the ages has consistently been used to motivate populations to reject reason.
Actually one of them (Sam Harris?) has pointed out that the biggest difference between religion and these other potentially dangerous irrational faith-based ways of thinking is that for some reason it is supposed to be discourteously to openly criticize religious ways of thinking; for some reason, one is supposed to
respect irrational faith-based ways of thinking if explicitly labeled religion.
I can poke fun at a person's superstitious belief in a giant Invisible Hand That Regulates Marketplaces -- people might disagree with me, they might even call me silly, but at least it would be considered a legitimate discussion in political/social/economic discourse.
But if I criticize a persons superstitious belief in a Charleton Heston look-alike living in the sky who loves us and wishes he didn't have to send us to Hell, then I'm told that I'm out of line.
It's the idea that some irrational faith-based beliefs are supposed to have some sort of protected status.
In many respects, the Bible was the world's first Wikipedia article. -- Doug Brown (quoted by Carlin Romano in
