I mean, Don Cherry was voted as one of the greatest Canadians of all time. Not greatest Canadian hockey people, but Canadians in general. Like a million people voted on that so it's not some small sample size.
Cherry's show was wildly popular and successful for decades. His nativism was obvious the entire time.
Many of us said so on this very forum (where Don Cherry was, for years, the ONLY hockey commentator to have his own permanent sticky thread). It's not as if he said something dumb/racist/nativist for the first time in 2022 or whenever it was. It wasn't some shocking reversal of sentiment. It was perfectly aligned with what he had been spewing for decades.
So yeah, there are many millions of Don Cherry fans in Canada.
To put it in perspective, there are worse things in the world than sports nativism - although sports nativism can possibly be a symptom of larger nativism, and larger nativism may also be a proxy for racism. So it's just an ugly path to go down. And it's arbitrary as well.
