Really? When my son played competitive league soccer he got ejected from the game and sat a two-game suspension for mouthing off to a referee. Even at that, it took a couple of go-arounds before he finally got the point, that there was no percentage in mouthing off to a referee.
A one-game suspension in this case is the same as telling the kid that his behavior is acceptable. You'll do him no favors that way, and you'll be setting him up for something worse in the future. Not to mention the effect it will have on the mindsets of all the other players and their coaches. These athletes tend to be very brash and overly self-confident, and most have repeatedly had rules bent and broken in order to keep them on the playing field. It's a dangerous precedent.
Go back and look at the previous exchange. I said the kid committed felonious assault. When someone pulls off an opponents helmet and strikes them with it and causes and injury requiring ten stitches they require a harsh response.
I suggested someone who supported the thug deserved similar treatment and they challenged me. I said I’d gladly accept the same punishment they recommended for the original miscreant.
Now you know the rest of the story.
