We Americans take free speech for granted.But if you look around the world, you see why we shouldn't. In Britain, you can get arrested for saying things online that police find “offensive."In Scotland, misgendering someone can land you in jail for seven years.Canada may soon pass a law that would punish “advocating genocide” with life in prison.Now in the U.S., the House of Representatives voted for a bill that would make chants like “from the river to the sea” illegal at universities.These are bad ideas.Free speech is valuable.
