Then he said that he didn't "seek to impose my values on the rest of society by force of law". That means that he wants liberty, but doesn't want it imposed on the rest of society by force of law.
Then he said "The purpose of government is to protect our god given liberty.". That means that he wants liberty (one of his values) imposed on the rest of society by force of law.
If you don't see the contradiction, there's something wrong with your reading comprehension.
edit: Anyone who understands the difference between anarchism and libertarianism already knew that he was contradicting himself. Anarchists think that everything should be legal, including taking away the liberty of others. Libertarians believe that it's the government's job to protect our liberty. By doing so, liberty (a value) is imposed by force of law.
