I'll just throw this out there.

Sad how abusive "cheering" has become. If any institution actually cared about sportsmanship from its fans, it would actually enforce that lame "sportsmanship statement" that so many of them read before each game. You want to show you're serious about it? Start throwing people out without refunds. But nobody wants to do that at any level.
