Putting conservative bumper stickers on your vehicle around here means your car will eventually get vandalized. Not worth it. I generally avoid talking politics with strangers but if they open the door I will walk through and let them determine just how far they want to go. If they are a Lefty, the conversation normally doesn't last long since they normally get mad and stomp away. As a country we are divided even with regard to the most basic values that used to unite nearly all of us. That is why it is no longer working.
