Yeah I definitely think that was a good episode to do.
The only think I didn't like about that episode was when Savion called the other guy on the phone a jerk or something similar, or calling people stupid. I mean, I know the guy on the phone was clearly being horribly mean. And I know Savion is a young guy and it was the heat of the moment and that's a typical response he would give. I might have done the same thing. But I wouldn't teach kids to insult back like that. I would take them aside later and explain how to walk away from a fight, while still defending yourself. Plus, experts I've read about say to avoid speaking ill of people too much in front of your kids, because they will learn that behavior. Of course, I didn't see the whole episode, so maybe I missed something,
You don't have to be friends with people like that, but everyone deserves respect, whether they respect you or not. It's no great achievement to only be nice to those who are nice to you. Plus, insulting back and forth like that can make the situation worse.
I know this isn't Sesame Street, but in The Muppet Movie Kermit tries to reason with the villian at the end, to appeal to his humanity. It didn't work in that case, it doesn't always work. But sometimes it does. It's important to try.
