… Journalists Against Free Speech.

… all editors and publishers can take a couple of basic steps. One is to concentrate on hiring journalists committed to the most important kind of diversity: a wide range of ideas open for vigorous debate. The other step is even simpler: stop capitulating. Ignore the online speech police, and don’t reward the staff censors, either. Instead of feeling their pain or acceding to their demands, give them a copy of Nat Hentoff’s Free Speech for Me—but Not for Thee. If they still don’t get it—if they still don’t see that free speech is their profession’s paramount principle—tactfully suggest that their talents would be better suited to another line of work.

If your only response to ideas you disagree with is to have them banned, there's a damn good possibility you can't defend your own ideas.
