Of course – as does every sensible person. That’s why Canada’s hate speech legislation applies to nothing but the the public propagation of the most pernicious and unfounded hatred against people based exclusively on their skin colour, ethnicity, religion, or sexual orientation.
There is no absolute guarantee of freedom of speech, anywhere. Even in the U.S., certain utterances are criminalized because it’s common sense that the harm that they may cause outweighs the benefit of allowing their expression. In the U.S., you’ve had the (rather vague) standard tests of “clear and present danger,” and later “imminent lawless action,” which is the current test.
History shows us that scapegoating minorities leads to acts of violence against them. The law is a check against this. In my opinion, it is certain to reduce harm to innocent people and thus make life better for the public in general, which is what good legislation should do.
Here is an example of the sort of speech that this law covers. (WARNING: Extremely offensive, racist crap.)
It’s a song with lyrics that spread the meme that welfare benefits are extended to african-americans and withheld from caucasians, thanks to MLK and the NAACP, that it’s black people’s fault that white people are poor. The narrative voice cheerfully suggests that shooting black people in the head is the way to correct this imaginary situation.
An absolutist approach to free speech means that it’s (of course) legal to publish and distribute this song. There’s nothing illegal about putting it on the juke box in a bar. If a stupid drunk who’s lost his job to drink, used up his welfare bennies and is pissed that he can’t afford to drink anymore gets a case of the “thems” after hearing the song and murders a man, well, that’s just too bad. He oughtn’t to have been so suggestible.
Racist propaganda has a social cost. Sometimes rights need to be balanced. The 13th Amendment was regarded by many as an inexcusable abridgement of some people’s property rights. Well, yeah, it took some rights away. It was still good legislation.
Individual rights end where other folks’ noses begin. Canada’s hate speech laws are based on the idea that the narrowly-defined type of speech that they apply to results in real harm to Canadians if allowed.
