An internet shock site is a website created by evil neocons, usually containing a repulsive or disgusting image or video. The goal is to trick the liberal into believing that censorship is a good thing and necessary to protect our children for such horrid images or videos, while in fact the opposite is true. Furthermore most of the time the people in those terrible images were forced to do these things by the neocons.
It is a truly disgusting form of hypnoses and Brainwashing. They freak you out.
An example of a shock site is Conservapedia.
