"But political correctness is silly, nothing more. It starts with a humane instinct, not to offend, and takes it too far. The response is to educate. For example, unless all lives matter, at any given time, any particular group's lives are in danger of not mattering. Put differently, unless all lives matter, black lives do not matter, and unless black lives matter, all lives do not matter. The response is not to create a political movement whose principal object is to be offensive."
