I recently found out that a cousin of mine, about 15, is being brainwashed by his parents into accepting all sorts of religious dogma and nonsense. Now, personally I don't have anything against religion in principle, and I even think the Intelligent Design argument is, well, intelligent (or at least clever). But for a 15 year old to be indoctrinated like that bothers me. Is there anything I can say (or books I can recommend to him) to him that would not be insensitive to him or his family but would at least get him thinking about things in a slightly more independent manner? Thanks!
