We're all familiar with Political Correctness.  It's the predominant theme on Television & Media.   Political Correctness also rules our scholastic curriculum.   But, you should be made aware of its true origins, as well as the underlining purpose. 

It really shouldn't surprise anyone to learn that it was designed merely in order to create conflict & discontent.  This is not simply a matter of opinion.  But instead, it derives from a carefully planned attempt to destroy our society while also curtailing free speech.
So, if you always considered P.C. as a form of hostility, you were 100% correct.
