One of the Communist Goals compiled by the KGB over sixty years ago was to replace traditional art with meaningless “symbolism” as displayed by the paintings of Communist Salvador Dali, and shapeless, meaningless sculpture of beams and points, etc., and non-rhyming, vacuous poetry ala Toni Morrison, Bill Clinton’s poet laureate. Of course, all this non-art was widely acclaimed by the Leftist media and bought for millions by the upscale Useful Idiots.
The purpose is to distort and corrupt our cultural history and its strength. What you are seeing now is simply a continuation of that. There is also an element of another Leftist tactic - create chaos and violence in order to engender fear and a public outcry for a larger government presence in our lives. That is also why you are discouraged from protecting yourself but to instead call the police.
It hurts when I think of how many Americans support communism.
