I never said I wanted to do such a thing. I would never assault, threaten, personally attack, shout profanities, or throw anything at any other fans. But I would do my best to make sure they have a HORRIBLE experience otherwise in all things related to the game itself and make them never want to come back. These people didn't come to our building to play parcheesi and hold hands. They came here to root for the other team in OUR BUILDING. I will absolutely go out of my way to rub it in as much as possible when our team does something good. When we score and there are fans of the other team sitting around me, I will make sure to yell "You suck!" right in their general direction. I'll go to high-five fans of the other team as they leave early because they're getting whooped. And I will yell "You can have it!" during the Canadian anthem. I'd expect the same if I went into their arena.
I seriously hope you only act like this to people who are a$$holes and not to people who are just minding their own business. I go to many road games and I show respect and I get respect back.
