Is it just me, but have you also witnessed this kind of attitude againts psychedelics in mainstream media?
RAW: I coined the term irrational rationalism because those people claim to be rationalists, but they're governed by such a heavy body of taboos. They're so fearful, and so hostile, and so narrow, and frightened, and uptight and dogmatic. I thought it was a fascinating paradox: irrational rationalists. Later on I found out I didn't invent that. Somebody else who wrote an article on CSICOP, that's the group they all belong to: Committee for Scientific Investigation of Claims of the Paranormal. Somebody else who wrote about them also used the term irrational rationalism. It's a hard term to resist when you think about those people.
