Nothing scandalizes a leftist like the truth. Point out that women and men are different, that black Americans commit a disproportionate amount of violent crime, that most terrorist acts are committed by Muslims, and the Left leaps to its collective feet in openmouthed shock, like Margaret Dumont after a Groucho Marx wisecrack. This is racism! This is sexism! This is some sort of phobia! I’m shocked, shocked to find facts being spoken in polite company!
No one is really shocked, of course. This is simply a form of bullying. The Left has co-opted our good manners and our good will in order to silence our opposition to their bad policies. The idea is to make it seem impolite and immoral to mention the obvious.
