Makes perfect sense.  Both car owners believe in freedom for all, but only one is willing to do something about it.

Seen today as I walked to my car in the parking lot in Westlake Village (Ca). Of course, just next to it on the bumper’s left side was “coexist.” What I didn’t notice until I pulled away was that the car on the other side had a brand new–not kidding–“W ’04” sticker (the car was less than a year old). As I drove home I tried to imagine a bumper sticker that I’d put on my own car. Couldn’t think of one. New game, right?
