Bipartisonship Sucks

Why are people always complaining about all the arguing that goes on in Washington? I thought that one of the purposes of our political system was to allow conflicting viewpoints to be expressed. When people are entitled to argue and seek compromises that suit them aren't we free? Aren't we slaves when everyone must agree with a single party line? Isn't it true that on occasion we cannot compromise with those who hold opposing views? A good way to get seriously injured is to compromise with someone who wants you dead.
