This is the truth...fans of all different teams can be obnoxious. I agree that there are many Flyers fans who fit in this category. It's a shame when a handful of fans blow it for the rest of us and give us a bad name.
I have been at many games where I leave annoyed with the Flyers fans around me! I remember this one game, I was in front of this young couple (maybe around 17 years old), and the chick was just yelling awful things. She also knew NOTHING about the game of hockey. It's "fans" like them that I can't stand, no matter what team they are pulling for.
I personally respect (or try to) all teams, whether I like them or not. I also love the sport, so I will watch any game that I can, even if the Flyers aren't playing.
