A lesson for all: the bigger man does not quit, does not keep quiet, does not pacify in the face of evil. Contrary to the truthisms about being the bigger man - fighting for what is right is almost always the right move.
It is often said one should be mature and not "play the game." But the truth is, evil affects us all and isn't confined to isolated games. If you don't stop it locally, it will spread like a poison globally.
Learn from my mistake. Play the game, fight, dont quit.
