You gotta remember the average 'layperson' is just as smart as you. Do you need people worrying about what information you see or hear? It's like worrying people will be corrupted by South Park, gangster rap, etc., etc. There's plenty of crackpot doctors that make all sorts of claims- is it blasphemous to doubt that the Food Pyramid, and three meals a day, are the correct way to eat? People can handle their own shit.
