A democracy cannot survive if there is constant talk of violence towards others who disagree with our own ideas. That will eventually lead to the breakdown of society. It will only take a small event to trigger the violence that all the violent speech has been building up to within society. History has too many examples of what happens when bullets and carnage replace words and debate.
Learn from history people. Palin and any other backward, violent politician, left or right, needs to go be ostracized by those who hold democracy and the union sacred.
