Call it a crutch if you want, Mr. Ventura, but some people still need religion. When Marx said that religion was the opiate of the people, he was right. Not in the sense that it was a mind-controlling force, but in that they make it easier to bear the pains of life. I believe they don't need it, but it would be cruel to take it from them. Likewise, it would be cruel to let people fall for potentially dangerous cults.
Religion is mostly benign, albeit frequently destructive.
Just keep them all, cult or not, out of our science classes, and I'll be happy. Maybe then we'll get out of these damned Dark Ages.
