The truth is that you can hold the opinions of messageboard warriors against an entire population if you'd like and get the worst impression of any fanbase if you did so.
There's no denying there's keyboard warriors that hold Canadian franchises to different standards than American franchises.
But there's also no denying there's keyboard warriors who pretend that only one side is "provincial" which is absurd. I've seen plenty of that on all sides.
I'm sure a quick deep dive search would find plenty of people saying "all Canadian teams sell out all the time" or other such ridiculous hyperbole. Flogging those fans, to me, is like flogging a strawman. And I'd take no pride in winning an argument with such dim people.
But also to rest one tired counterargument: I lived in Atlanta during most of the Thrashers' time, was p!$$#d at the NHL's indifference when they left and still think that market could make the league beaucoup bucks if done right. I like to think of myself as much more pro Atlanta than anti-Atlanta. But whenever someone points out Atlanta's attendance, and the natural Atlanta rebuttal comes "but Boston, Chicago, etc. had bad attendance for x, y, z years and we don't make fun of them because traditional," I cringe at how intellectually weak of an analogy that is.
Cities like that have whole decades of history of selling out the joint and in some cases, more than a century of history. It's not remotely an apples-to-apples comparison. As far as attendance for Atlanta goes, the best you can say for the Thrashers is: a--- They set an expansion attendance record which was broken by Vegas, b--- they were...an 'OK' attended team when doing well. The highest they were ever ranked in the league, despite having an arena capacity that would have capably supported being in the Top 10, was #11 (their first year). The best you can say for the Flames is: They never set the NHL on fire as an attendance firehouse but they were miles better than the NBA Hawks when taken cumulatively from 1972-80. And we have zero evidence they ever broke through on television (which is the biggest reason you would want a team in Atlanta in the first place).
So it's NOT true is pretend they were like Boston and Chicago at every market's peak. There's zero evidence to support that. It's NOT a strong counterargument to say "we give Boston, Chicago, etc." excuses. Those markets get excuses because they are very different markets historically (mostly for reasons that aren't Atlanta's "fault" per se but nevertheless are very different).
Now mind you, there's also zero way of knowing how Atlanta would have done if either the Flames had turned out like the Islanders competitively or if the Thrashers had turned out.........like any regular playoff team. Or if the Thrashers had ever had anything resembling competent ownership. That's the argument I keep trying to make whenever I wade into this: ANYONE PRETENDING TO KNOW WITH 100% CERTAINTY WHETHER ATLANTA CAN SUCCEED OR FAIL IS LYING. Because we don't have enough evidence to see that they could be the "talk of the town" (their best attended years were "mid" at best) and we also have next-to-no evidence of a properly run franchise in the city (...but their "best" years weren't all that "best" and in fact, if you draw a line from the first Flames season to the last Thrashers season, the ownership gets progressively worse).
Bringing it all back to Winnipeg, I think any fan that thought the Jets would sell out in perpetuity was lying to themselves. But saying it's not right that we "treat" Winnipeg differently? Well........we should treat Winnipeg differently! It's a very unique market. I wouldn't judge Atlanta by Winnipeg's standards or vice-versa. I think each market brings something very different to the NHL. FWIW, I feel the same about American markets like Columbus or Florida (Sunrise). In Winnipeg, what we judge differently is the market's interest in hockey. We know hockey is Winnipeg's #1 sport: The TV ratings in that market as compared to southern teams that struggle will bear that out. But does that mean that Winnipeggers have sufficient capital and passion to sustain mediocrity over an extended period of time? Who can say......not looking good in a small sample set this year, let's see how the next five years play out.
