[Ghoulish Delight]

A sporting event is not government funded.

While I agree with Alex that since the football game is not required, and the sign was likely the idea and creation of the cheerleaders, not school officials, it's low on my scale of offense. But I'm generally incensed at how much of schools' budgets are dumped into football while other core educational necessities are monetarily choked to death, so that reduces the amount of slack I'm willing to give to people privileged to be participating in said public money sink.
