[Mark Mercer, Ottawa Citizen] Now on the other side, to balance against all this, is harm, the harm that expressions of hate cause vulnerable people. Restrictions on expressions, most of us can agree, though some of us will agree with regret, are justified when they are needed to protect people from harm.
For a restriction on expression to be legitimate, though, there must be good reason to think that its presence will indeed prevent harm. Harm, moreover, that cannot be as efficiently prevented any other way. In addition, there must be good reason to think the restriction will not create more or worse harm than it prevents.
The rest.
