One of the ways to avoid getting angry is distancing from things or situations that could warrant it. You've done well to consider and do that. But then, trouble will still finds its way to you no matter how peaceful you are. I guess I'd would have been surprised by your action too. They pushed you, and that doesn't sit well at all. Your response was extreme and would have been regrettable though, but thankful for external interventions. Continue protecting your peace man.
