In a political context, the word 'censorship' means coercion used against non-coercive communication.
Libel, slander and the way-too-often-cited-but-misunderstood shouting-Fire!-in-a-crowded-movie-theater are all examples of fraud, which is coercive communication.
Flag-burning, cross-burning, and the infamous N-word, are (in and of themselves) non-coercive communication, no matter how much people may be emotionally hurt or offended by them.
