Given that China is clearly at war with the U.S. (and freedom everywhere), it would be illogical to conclude that they ARE NOT funding internal strife of the Marxist/Maoist sort in the U.S.
They may be communists, but they are stupid. Quite the contrary.
They have a long history of manipulating the race wars, sometimes gently, sometimes with great enthusiasm :
The Communist Party USA created Freedomways magazine as a propaganda vehicle with which to reach into the black intellectual and academic community. It was established in the mid-1960’s by members of the CPUSA and well-documented sympathizers/supporters. It billed itself as “A Quarterly Review of the Freedom Movement.”
Newly declassified documents from Operation SOLO, an FBI program to infiltrate the Communist Party USA, reveal that a journal called Freedomways, which was influential in the black community for decades, was subsidized by the Soviet and Chinese Communist Parties.
Freedomways has been called “one of the most influential African-American literary and political journals of the 1960s and 1970s.” It began in 1961 and ceased publication in 1986.
During the 25 years it served as a propaganda organ for the CPUSA and Soviet front organizations such as the World Peace Council, Freedomways published articles by such figures as:
Derrick Bell, one of Barack Obama’s academic mentors and a Harvard professor;
Martin Luther King, Jr.
John Lewis, a Democratic member of Congress from Georgia
Jesse Jackson , a former aide to King and Democratic candidate for president. [8]
