Is too much Fanaticisim with sports matches expected?

I'm one of those avid fans of basketball. I also get crazy over a game especially when I watch it live. I cheer for my team with my lungs and heart out every game. But of course, I know, people just like me should also have some considerations for the people who doesn't share such devotion as yours. ^_^

Yes I do anticipated basketball games like NBA Playoffs, Philippines Basketball Association Playoffs, PBL Playoffs, Chelsea Team in soccer they have an important game. Cricket is famous in India, Pakistan and Bangladesh.

I think it's good if we become a fan of any sport. Enjoy it as much as we can but that's all. I hate to see sports fans that fight with one another when their teams win or lose. Sports are suppose to bring us together, despite any team that we support. If our team lose a match, accept it.
