The Canadian hockey media has a decades-long well-established pattern of nativism and anti-Russian bias. Don Cherry is not some new thing. He was/is wildly popular in Canada and it's not some leap in logic to say he was a nativist.
Cherry is an undeniable one of a many examples.
It seems to me you've been beating this to death for years now, and it's full of holes.
You're right that Don Cherry is not some new thing -- he's OLD and OUT OF DATE. Cherry's influence (an overstatement) in the Canadian popular culture peaked about 30-35 years ago, sharply declined thereafter, and is at zero today.
Cherry's viewpoint in the media was always exaggerated, an intentional self-caricature, and played for attention (i.e., ratings). It wasn't even an accurate depiction of Don Cherry's
own views, let alone millions of other Canadians'.
There's video online of people like Maurice Richard in the 1960s talking about how he respects the Soviet style of hockey. In 1972, millions of Canadians were impressed by the Soviets and lauded them accordingly, including NHL players and executives. In 1981, after that piece of s*** Alan Eagleson denied the Soviets the actual Canada Cup tournament trophy, the good Canadian people of Winnipeg banded together, paid for and made their own replica trophy, and sent it to the Soviets. Excellent showcase tournaments like Rendez-vous '87 showed the mutual respect and appreciation between Soviet and Canadian hockey. The game's greatest ambassador, Wayne Gretzky, consistently praised the Soviet/Russian players in his era, visited the Soviet Union in 1983 and invited Soviet players to his Brantford family home during Canada Cup '87.
The whole idea of a Canadian media bias affecting the NHL today is a stretch, at best. For one thing, less than 22% of the NHL clubs are Canadian franchises, so if some sort of Canadian consensus were trying to twist award-voting or player-recognition, it would face a battle vs. the 78% non-Canadian majority.
A half-century ago, a Finnish defenceman almost won the NHL Norris trophy, while shortly thereafter (still in the 1970s) Swedes became the toast of a Canadian city like Winnipeg, where they were the local superstars. Swedes are so popular in Vancouver they might as well re-name the franchise after them.
Russian superstar players have perhaps been less well-represented in Canadian franchises than American ones, but that's par for the course with
all superstars since 1989-90, when ex-Soviet players first arrived --- because (a) a vast majority of clubs are American, and (b) more free-agent contracts were signed in the more lucrative USA (esp. in the 1990s and early 2000s, when no players, including Canadians, wanted to sign with Canadian franchises).
I mean, almost 30 years ago an ex-Soviet won the Hart trophy and Selke trophy in the same season.
