The system is intrinsicaly racist as It is normally, in a moral acceptable way by most people, you are not imprisioning Black people and latinos, but criminals. Then they say Race is not a factor when It is.
What fascism does, its that it gets the system that already exists with more energy and authoritarism/totalitarism, saying thats the only Way the system can work, is with more strenght, violence. Then there's two types of fascists govermnents the Way i see, the openly racists, racial supremacy (nazi). The other that does not say that openly, but is (Basic fash)
Fascists have the advantage that they already have the system in today's world already done, and their defense of the elite makes It easier for them to be accepted. Then they reinforce the prejudice to communists, Blacks, jews, romani etc, to have a scape goat of the system.
Thats How I understand It.
