Sad, but true. As much as I laughed, sneered, rolled my eyes at "I'm With Her" or "Obama/Biden" stickers I never considered doing real damage.  Today's leftists genuinely think they're in a post-1920 European Marxist revolution where the ends always justify whatever means necessary.  It's more than a meme or talking point: they really are dangerous.    It's been some time since I last felt this way, but I'm seriously considering putting a tool in the trunk of my car for daily travels, something more than the tool I keep on my hip.
