"Free speech" sometimes collides with "Hate speech"... and when this happens, "hate speech" should back off.
No society should tolerate the exposing of any individual(s) to hatred and danger of injury, physical or mental. Otherwise, what is the role of society? Those who think they can say what they want, when they want and way they want simply must try to imagine themselves as target of hate speech.. consider the consequences of those actions... and take responsibility for them.
And/or they can go to the bush, and live alone, they are not constructive elements of society anyway.
