In fact you should unfriend him on FB (quietly) or AT LEAST hide him so he doesn't turn up in your feed.
Here's a Harry Potter reference for you: Never tickle a sleeping dragon. Why would you start a fight about Facebook? It won't get you one thing that you want, will only provoke him to more spitefulness and make you look petty and controlling. You have enough problems with him.
If so many people think he's being disrespectful and pathetic then just let the show go on. It only hurts you if you let it.
