It wasn't a picket line -- it was a war protest. I sat at the red light and stared with disgust at the moronic messages scrawled on their signs. Our military toppled two murderous dictatorships to make way for free elections and these asshats still ask the rhetorical question "what are we fighting for?"
If the boys were a little older I'd drive them up there for a teaching moment:
Sons, there will be moments in your life when you or your loved ones are threatened with violence of some sort. At those times you will need the support of the clear-thinking and courageous citizens of your community. Those people you see across the street holding those signs? People like them will be of no assistance.
