In other words, all laws restricting free speech are justifiable because they are laws.
Second, “if the speech may cause danger to public safety”. Granted, this is a well-accepted restriction on free speech.
Third, “a speech is not an academic exercise in search of truth if it is one-sided and does not include different or opposing perspectives in appropriate detail”. In other words, no one should be allowed to express their own views without also expressing all other possible views in detail.
By this standard, Professor Ng-Quinn’s letter on “free speech” is itself not in search of truth (since he does not consider any opposing perspectives) and it would be justifiable to restrict his right to express himself in this way.
