https://en.wikipedia.org/wiki/Intersectionality
"It is the study of overlapping or intersecting social identities and related systems of oppression, domination, or discrimination. Intersectionality is the idea that multiple identities intersect to create a whole that is different from the component identities."
Seem like the article is pretty accurate to me.
Seeing as how the "Red Scare" has pretty much tainted anything to do with Marxism/Communism, I'd say "regressive left" is a little be easier to use.Also I think the in-vogue snarl term is "regressive left" because "cultural marxist" sounded way too stupid.
