Uh?
If you don't like the term ''Neo-Marxist'' and prefer plain Marxist, fine by me. Makes no difference. Given that Marxism was more concerned with class discourse while intersectionality uses the same matrix of oppression with focus on the intersections of race, gender and sexuality, I call it Neo-Marxist.
I'm not really interested in the triviality of the name anyway. My point doesn't change. Do you want your party to run with a Marxist framework? Great!
