First of all I do not recall anyone threatening revenge. Secondly, it is not one incident. This type of behavior is typical from that team. That is the point. Thirdly, you are judged by the ones you associate with. Posting here is not an example of bad sportsmanship, we are concerned for the welfare of the kids. When you have coaches teaching technique that is dangerous and illegal and that it is okay to use it, we have a legitamate right to be concerned.

You are right you don't tear down the child. But the coaches are guilty of positively reinforcing the actions of the children. The actions that the coaches are teaching. The coaches are supposed to be role models for the children. When the coaches are giving "high fives" after his wrestler has injured another wrestler, of course that tells him that it was okay and is okay in the future.
