Because of crap like this.
Oh, and I will refuse to hire anyone with a "gender studies" degree, a degree with anything LGBTQXYZODQICANTEVEN. If the person supposedly teaching the class says "I don't use gendered pronouns" get up and walk out of the class. There's a place in this life for make-believe. That place is with children. If your professor wants to play make-believe with their biology, that puts them on the level of children who cannot understand simple things like male and female. You don't need to be taught by adult children.
