I, a PhD student, had an intro lecture on gender and post-colonial theory for our bachelor students. During the break a young, male student came forward and explained to me that all women are average intellectually while men are both the dumbest and the smartest in a population. His source: A graph he had seen on the Internet. He even drew it on the white board for me.
And yeah, he was studying to become a librarian.
Good luck with that!
