I'm an INTP libertarian.
This is a Libertartian's view of the proper role of government:
1) ensure national security (obviously, this task belongs to the feds);
2) create and administer a justice system that redresses criminal and civil wrongs; (e.g.,protect individuals from force and fraud, enforce private contracts, compensate for negligence)
3) protect its citizen's freedoms in general.
All other governmental functions (e.g, the forced redistribution of wealth, educating our youth, running the world's largest Ponzi scheme, social security, need to be reevaulated.
Please understand that libertarians are not anarchists; we simply adhere to the credo: "The government that governs least, governs best."
