So, I was driving with my 18-year-old son today, and we pulled up at a traffic light behind a car with its rear-end so plastered with bumper stickers, I couldn't tell what kind of car it was. After a few seconds, my son asked "What is it with liberals and bumper stickers?".
I explained to him that true liberals have to embrace not just three or four liberal ideals and myths, but every stinkin', fetid one of them. That requires a lot of bumper stickers.
