It's more than likely some stupid ass liberal arts class. My university had something similar and they made tshirts that said "women = power". It was the absolute worst seeing them parade around campus, and of course there were the simps that wore the shirts too, thinking it would gain them favor with the women. Not once did I see any of the dudes with a girl that I can recall though lol.

Its absolutely ridiculous that such a thing like that should be allowed, let alone encouraged by professors at school. All it does is teach one side to feel empowered and better than the other, and makes the other side (especially the already insecure) feel belittled. It's pure and blatant sexism.
