It is a fairly straight line from Marx & Engels, to Lenin, to Stalin/Mao/Castro, to the Frankfurt School behind the Berlin Wall, to Herbert Marcuse, to Communist Party of the USA twice Vice Presidential Candidate Angela Davis whom disbanded and merged into a new creation and giving it the name, the Committees of Correspondence for Democracy & Socialism (CCDS) to BLM and trained Marxist Radicals Patricia Cullors and the other 2.
