It’s great to belong, to be part of the tribe. Sports do this, who do you support? Though what happens when the answer isn’t your team? In what stead do you hold the other person now? There is potential to slip into ‘for and against’. If your not with Us, you’re against Us. There is another view, we get to play the sport only because your team exists as we need at least two teams to play. How about that it’s in your interest to keep others in the game, to spread the cause.
