We take free speech for granted in America, unlike elsewhere. The furor over that anti-Muslim video is the latest reminder of that. But freedom of speech is never safe, even here. Many colleges now impose "civility codes." Civility is nice, but enforcing a "civility rule" against offensive speech would put an end to lots of useful provocative speech.
Instinctively, we look for people's motives. We need to know whom we can trust and whom we can't. We're especially skeptical of business because we know business wants our money.
