It’s odd that you use this metaphor, I consider myself to have mastered “racial” calculus, (because I have an identity which I call “swirly,” I’ve been in predominantly white situations as well as predominantly black situations, I understand how both speak (or for most white Americans) fail to speak of racial divisions in America.
But I would posit both groups, black and white, are primarily on basic arithmetic in this regard. I’m constantly doing calculus. I’ve had a career that has forced me to do so. (EEO attorney).
But…when it comes to sexism, especially the sexual exploitation, ingrained in sexism…are black women doing Calculus? They may very well be! I’ve never thought about it, in that way…you might be right!
