From the little that can be gleaned from the video, it appears that the son has learned from the parents; something about shoving a girl. However, while all the focus is on the "altercation", it would be good to know more about why these parents were so upset. Are they simply aggressive people that act out when things don't go their way? Probably. Is there more to this story? Yes, yes there is, and we don't know what that is. It's easy to put the blame on the aggressor, and that may be correct, at least in part if not full, and yet we all also know there is a lot of nonsense going on in our schools these days, so it would be better to understand all of the circumstances around this incident before we pass judgement.
