It is that sentiment which leads me to believe that libertarians are short-changing themselves in this entire movement. Human beings are not exclusively economic agents. We're much more complex than that. This movement represents more than just economic reforms and liberties, and the problems we critique go much deeper than many libertarians are willing to admit. As AquaBuddha2010 has said, this is a moral battle we're in.
I would add it's a war of worldviews, ultimately, the Kingdom of God versus the kingdom of man. So, in that sense, the Tea Party Movement needs to get back to the elementary principles which our Founders pointed to. It all begins with the sovereign God Who created us and endowed us with our rights. Any movement that takes God out as the foundation of its projection is a movement walking closer to a sepulcher. Sadly, most libertarians treat God as an insignificant Being, and to that, their ruin.
