Interesting! Agreed, mistake to conflate Marxist work w/ political-theoretical movements now popular. Their effect largely reorienting study. Getting more folk to pay attention to (e.g.) living conditions for slave women count as contribution? + things learned as a result of this
( Other than, obvs, my own studies on formal methods of studying intersectionality theory, which I am sure are going to revolutionise Western learning and the epistemology of science any day now! ;) )
