David Brinkley once said; "The news media can't tell people what to think, but we can tell people what to think about."
The capability to tell people what the important issues of the day are, is an even more powerful tool of manipulation. It is up to the free-thinking person to evaluate and assign for himself what the important issues are.
Case in point:
Politically correct speech is a tool designed to win an argument before anyone opens their moth to speak. By demanding that a person use your approve terms and definitions, you succumb to their designs and walk right into their carefully-laid trap.
This political correctness madness now ties liberal journalists in knots. When a black man in London attacked a British soldier, he was described as a "British African-American". Never mind that the machete'-wielding Muslim was a native of Ethiopia. The journalist had lost the ability to think and speak. She was following the mandated protocols of her news outlet. Somehow America was attached to the identity of the decapitating monster.
Does CNN really want to proselytize the nation to Islam? No, but they hate evangelical Christianity more, so they tolerate Islam. They celebrate any attempt to magnify the image of anything which is in opposition to evangelical Christian teaching. Liberal media is perhaps the most hateful institution in the nation. Sadly, some Libertarians are caught up in this war on Christianity and have lost sight of the libertarian values they historically have championed.
