Christina Hoff Summers explains just what “intersectional Feminism” is, and by extension, what the entire Leftist idea of “intersectionallism” is.
At it’s core, intersectionalism is a way to point out different “original sins” in people and have them serve your purpose, if you are a Leftist Progressive, in order to shrive themselves of their original sin.
