It is very important to recognize the extent to which the movement for Negro equality and civil rights was infiltrated by Communists. In fact, the movement was to a great extent a Communist front used to recruit dissatisfied Negros and liberal whites into Communist ranks.
Do you have a larger point?
The entire New Left movement was a Communist takeover of the old Democrat Party. It was an outgrowth of the Communist "Progressive" movement of the '30s and '40s which created many propaganda fronts. One assumed the public face of the MLK civil rights movement but was manipulated by the New Left. Instead of the MLK dream we got the racist Black Panthers and their violent Communist spawn like Malik Zulu Shabazz, leader of the New Black Panther Party that interfered with voters in Philadelphia.
