I think Marxism has a minimal impact on relations between the various demographic splinter groups. Marxism has long passed its prime. There may be a few dumb heads who still accept some of its tenets.
Amongst the groups themselves perhaps, but it is still the meme/basis for the oldest tricks in the book on race baiting, socialist mumbo-jumbo. To wit, Mugabe. To wit, Julius Nyere’s Ujamaa one political party totalitarianism. South Africa and Mandela. Cote d’Ivoire. Liberia. Kenya.
Obamaumau is in Africa assisting the goals of either the chicoms or the soviets.
