Fettering freedom of speech
Bad idea.
The courts have no framework for responsible use of freedom of speech because there is no legislation covering it.
The current legal restrictions are to do with inciting racial hatred or criminal acts. Some piece of rushed through legislation covering a narrow area should not be used to introduce major new directions in such a fundamental area of life.
The EU would like to introduce restrictions on criticism of government institutions on the grounds that they undermine confidence in public institutions. Various religious groups would like to shut you up with new blasphemy laws to stop all discussion of the rights and wrongs of their various agendas.
And the standard they all plan to use is "causing offence". If you can get enough of a constituency to say they are offended you can shut up all your critics.
And all this is apparently OK to some because at least it shuts up some mindless troll.
