We the People, you and I, shut down the government. I blame us because Congress represents us and our opinions.
The problem is that we turn complex ideological debates into simple, black and white statements: "Defund Obamacare! It's socialism in its evilest form and will bring America to its knees." "Whoever doesn't support Obamacare is heartless and doesn't want sick children in America to be happy and healthy."
The debate over Obamacare isn't that simple, but trying to turn it into such a simplistic issue makes it dramatically more polarizing where compromise seems like making a deal with the devil. However, our job as Americans is to fight our natural urge to take this easy, simple road.
