Hmm, it is true that people have been dumbed down a lot over the years. People are dumb as hell. But so too, humans are a social creature that seeks the approval and admiration of its kin, therefore the controversial human will be alienated and pushed out of social circles. People who don't follow the crowd get singled out because they aren't one of the sheep. Stupid people still have basic social psychology that deters anyone from steppinh outside of the norm.
