They are contaminated; they are programmed to think and react to certain stimuli in a certain pattern. You cannot change their mind[s], even if you expose them to authentic information, even if you prove that white is white and black is black, you still cannot change the basic perception and the logic of behavior. In other words, these people… the process of demoralization is complete and irreversible.
-Yuri Bezmenov (KGB defector)
"Do not give dogs what is holy; do not throw your pearls to pigs. If you do, they may trample them under their feet, and turn and tear you to pieces.
