Some parents get very, ridiculously caught up in the excitement of their kids' sports, and a very small number go too far. I have seen parents fighting in the stands at 10U football games (10 and under). I have heard parents screaming at coaches threatening to sue them. I have seen parents mocking and degrading the opposing team's kids. I have seen parents encouraging taunts and chants from the crowd to throw off a pitcher or a quarter back. I've seen a nasty, abusive man ejected from a high school building entirely for cursing and screaming at opposing kids. And of course we had CPS called on us.

It's only a very small percentage, but they really ruin the experience for everyone.
