I agree with Rags and Flyers, but not Habs. They're loud, they invade the arena, and they love their team, but they're not there to start trouble. I've had nothing but positive interactions with them. And I've had bad interactions with other fans.
I have to disagree. They are some of the most disrespectful people I've ever encountered. They sh!t on our national anthem and country every chance they get. Their self-entitled attitude has no basis in reality and is out of control. They are just as bad as Rags and Flyers fans in my opinion, but they just handle themselves differently (and, in typical French fashion, when you confront them, they back down).
I've relayed this story before, but at the last home game against Montreal last season, where the Rock had like 10,000 Habs fans in it, the row from Montreal in front of us started crap all night and gave teh Hitler salute when they showed the returning US soldier of the game on the scoreboard. When that happened, all hell broke loose between them and the four of us sitting behind them. They kept claiming they didn't understand English, although they were speaking it all night, and said they were stretching. Eventually, Security calmed the situation down. Unfortunately, this was not an isolated incident as I've heard from many people that this kind of stuff happened all over the arena that night.
