My biggest fear is media sponsored ignorance. The media (Fox, MSNBC, you name it) perpetuate a great many myths in order to get ratings. A great many of these myths are rooted in centuries old ignorance. So my fear is complicated further by the fact that the media works for ratings anymore, not the truth. So I fear ignorance, and I fear the media that cares not a whit about some of the garbage they spew.
