i see a fundamental difference in the understanding of what our government is or what any government should be. conservatives believe they can live without government which is contrary to how and why our government was formed.
the Founders believed government should provide services to its citizenry, and thus we find as a part of our contractual agreement that the government would do the following things defend etc if we agree to give up some of our inherent biological mandate to live within the bounds of a society which has an arching structure of government.
ironically both conservatives and liberals believe in essentially the same things. the real difference is the process of implementation.
