So if a black lib is quoting someone white and I don't like what he's saying, I can lay exclusive claim to the white guy by virtue of shared pigmentation, and prohibit the black lib from using the quote?
What would have really blown his gourd if the response would have been something like this: the only reason that you are a free man and have an education and have not been castrated and put up for sale in a Muslim slave market is because of Christian white people; they are the ones who started the movement to abolish slavery.
Some white leftists wrote some of Dr. King’s best known speeches or key parts of them. Soviet operative/Communist Party USA admitted member Stanley Levison was one of King’s top advisors, and wrote some of them.
I believe the guy who wrote King’s April 1967 anti-Vietnam speech was also white. Don’t recall his name right now but previously it was thought that Levison wrote it.
