I don't think anybody is judging all Americans by the actions of Chelios and Tkachuk.
As for the rest of this thread, here's my drive-by:
-there certainly are Canadians who resent or dislike anything American. I think that's a fact. It's unfortunate, and is pretty unflattering to Canada as a whole.
-there are also Canadians who were pretty happy to see Team USA knocked out of the World Cup. In hockey, they're a rival. I don't see a problem here. When Canadians think of US hockey, they think of every Woody Paige article blasting Canadian cities, every time a US fan reminded us who won World Cup '96, Ron Wilson and his "1972 made Canadian hockey complacent" take, every "Woe Canada" article written by an American media guy after all the Canadian teams are knocked out of the playoffs. It's a sports rivalry. It doesn't mean anything outside the realm of sport.
-many people on both sides of the border have believed that Chelios and Tkachuk were buttholes long before they refused to shake Vile Niemenen's hand.
-yep, Niemenen's a punk too, and one of these days he's going to get it. Hopefully it's via a fair fight or a clean hit.
-yeah, lots of Canadians (and people all around the world for that matter) were happy to see the US men's basketball team flop at the Olympics. When you're a bad winner, people will remember it when you lose. Doesn't have much to do with hockey, though.
