All of these are scopes that modern society hyperfocuses on when race or gender are involved. That's the hypocritical aspect of it.
What are you possibly going to do about it that isn't already covered under a more general and better fitting "lets find ways to treat each other fairly that minimizes the opportunity for our monkey brains to fuck up and associate traits and characteristics with superficial features. there has got to be a way to do this, jesus christ"?

Or Black, by the old American rules around race. I did say it's a thought-stopping category.
