Don’t Turn off the Projector
Only one type of speech is properly prohibited and that is speech which seeks to censor others. A person who advocates censoring others should himself be censored. Censorship is needed, many will argue, citing the example of the one who yells “Fire” in a crowded theater. A person who commits such an act should be punished, but his speech cannot be the subject of before the fact censorship for the simple reason that it has not yet occurred.
