Literature has been around since man learned to write, and with a little hope it will be around for many more years to come. That is, however, without the aid of biased censorship. An article exposing something or calling someone something can be your ticket to activism. Violence accomplishes nothing in the long run, and it's the path of the ignorant. More than you think.
Violence is popularized by many different medias.
It's an informative media for the betterment and structure of a social being. The media can stir the feelings of people and make them believe half-truths. Stories like school shootings are great opportunities for the media to pick up on and live off. A certain glorification of criminals is reached through the television media. The Texas Seven, for example, only spoke with the media on the end of their pursuit.
