I don't think a person can call oneself a libertarian unless they legitimately believe that every aspect of government ought to be minimized and not expanded in any way, shape, or form -- hence why I stopped using the word to classify my ideology a long time ago, but that's just me. 
There are some functions of government that I have come to see as "necessary evils" and live with, but I still find it rather unsettling to actively
support government intervention in almost any area of personal or public life. I don't know what that would make me, but I have thought that the word "libertarian" is bantied about overmuch.
