I'm not talking about anything other than hockey-related issues when it comes to Canada. IMO, every country - more or less- has its own negatively "diagnosed" feature. When it comes to foreign policies, we all know the US is on the front line. And Americans tend to behold themselves as Goliath in many ways (and I would assume it's the same within the sport industry, for example regarding Basketball). The Swedish parliament, and many of the people in the country, believe their "humane" view on society and solidarity is the best in the world. China usually propagate for their "superior" gymnastics and Olympic contributions. When it comes to soccer, some nations are more cocky than others; for instance, Italy, Brazil, Netherlands and so on. And when it comes to hockey - the best sport in the world - Canada happens to be the cocky and "We are the best"-kind of nation, and upon which the one other nations look with a bit of disrespect and dislike.
A lot of sentences just to say this: You just happen to be the peeve in terms of hockey competition, just as Brazil, Italy etc is within soccer; and America is considered worldwide.
The problem, I suppose, is that you have so many fans that you will always - no matter what - be the "cockiest" nation, simply because you have more noticeable fans screaming, acting disrespectful etc. Just look at the gold medal game (or any game for that matter) - 80 percent were Canadians. And although I did see a handful respectable fans, you can't fail to take notice to the ones who do act insulting and ban-mannered. Although not being a majority, they give you a bad reputation. But that's not really the issue, they're just fans. However, the other problem is your media. I do know you don't agree with me on this one, but the hockey establishment with its Canadian "moguls" and media icons, announcers, radio hosts etc, often act with a sense of overconfidence, bragging, "big-head"- and know-it-all attitude when it comes to other teams and their players.
You can't help to notice how self-aggrandized they seem. And of course other countries have this sort of "problem" as well - but it is more prevailing within the Canadian hockey. As always, IMO!
