What is the Tax Day Tea Party about?

My oldest daughter asked last night if the news would cover the Knoxville Tax Day Tea Party. I told here that I thought the local news would cover the event. She then asked, "What should I say if a news reporter were to ask me why I am protesting?" Good question. I suggested she might want to say something about not wanting to be saddled with a huge debt due to reckless government spending and borrowing. Later I showed her the below graph. The point can't be more clear than that.
