I want to print this post from Popehat, frame it and mount it on my wall.

…Say that someone sues, or threatens, or abuses someone whose ideas you despise, someone whose good faith you doubt, someone working for political or social ends you are struggling against. If that censor is successful in any measure, are you harmed? Yes. You are harmed because the next censor, the one gunning for you or someone you agree with — is emboldened. You are harmed because people, in general, are deterred from discussing controversial ideas. You are harmed because when censors are successful, censorship increasingly becomes the norm, and the populace’s already tenuous support of principles of free expression ebb a little more.
