People seem to forget or not know that Canada is already in a grey middle ground where free-speech is limited, and hate speech is considered a crime. And so far, the fact that Canada doesn't take a free-speech-absolutist position on the matter doesn't seem to have led to the unavoidable-slippery-slope that free-speech-absolutists profess it should lead to.
I'm of the opinion that free speech is important but I think absolutism is a red flag, and here is a case where a pragmatic middle ground has proven to work out just fine.
