There is a huge, well-funded propaganda effort on the part of the various barbarities in the world, whether Islam, gay marriage, pro-illegal immigration, etc. By keeping the barbarities in front of us Mark is helping, grass-roots style, counter the barbarities with knowledge. He will hopefully help otherwise clueless people realize that there is a problem and to define the problem. Defining the problem is half of the solution.
Consider it this way. People buy lottery tickets because the coverage of lottery winners creates the false illusion that you can win. But if you saw a thirty second interview with all the losers and they ran twenty four hours a day it would take nearly a decade (for most lotteries) to interview all the losers. A failure to cover one side or the other results in a false picture of reality.
The media are controlled by socialists and crony capitalists. ISIS is killing Christians - they are doing the left’s work for them. Were it not for the unofficial media, most people would know nothing about ISIS’ crimes. Obama would have the cover to give ISIS all sorts of aid (much more than he already has).
