Just like the Talibans destruction of 800 year old Buddhist shrines.
Or like the Turks covering the art in Hagia Sofia...
The elephant in the room is the Marxist ideology, like a beast that the Left wants to shove down the throats of the American people. Candidates like Bernie Sanders and his indoctrinated disciples, live in the fantasy world on the Unicorn Farm and do not want the veil to be lifted that would reveal the fraud of their ideology. It is the Big Lie. The Marxist core does not want the American people to know the truth of what they are doing. This destruction of a historic mural is part of a transformation from a free America to a world of the past, where the elites control the masses.
