Three times in the past week, I’ve seen this bumper sticker and I was wondering what it means. It’s a white 12 on a black diamond. The diamond has a white outline and is on a black background. The sticker is about 3" x 3". The cars have had other liberal/atheist bumper stickers alongside this one (one car had a darwin fish, a flying spaghetti monster “fish”, and the 12).
Anyone have any idea?
