Sexist Jokes Promote Violence Toward Women

As readers know, I've been interested for a while in the use of humor (particularly satire) for social justice work, as well as understanding what makes racist and sexist jokes morally problematic (check out the philosophy of humor tag). Now Spanish researchers have done a study that suggests that young men who listen to sexist jokes somehow become desensitized to statements that justify aggression and violence toward women.

Surprising?
