So in essence, you were screwed. Either you retaliated and were no better than them. Or you tried being calm and you were a French surrender monkey.
It took me a few months to find the middle path. Which consisted of ignoring the ones in it for a fight, and trying to settle differences, in a calm manner, with those not in it for a fight. But like I said, I eventually quit because the ones looking for a fight kept on coming, and coming and coming ... endless masses of adversaries. Way too much to handle. The ratio was like 1 Frenchman against 10 Conservative Republicans, and in such circumstances it quickly gets too tedious.
disclaimer: I'm not zen at all, I'm just beginning to get good at knowing how to avoid getting into trouble.
