Woke history is just Marxism but replacing economic class with race
Exactly.
The essence of Marxism is that the world is divided into two static groups - oppressors and oppressed.
Using class distinctions to define the oppressed and oppressors didn’t work out too well in practice because members of the various economic classes were not static. There was and is a lot of mobility in economic status.
Race is a much better victim class for Marxist because it is easily identifiable and, most importantly, because blacks, due to their significantly, lower average IQ will always on average perform lower in life and thus serve as a ideal permanent “oppressed” class.
And if there is an oppressed class there must be an oppressor - and guess who that is?
