Excellent description! I would generally use the same one for myself.
IMHO, something we keep missing in this thread is the distinction between small-l libertatians who generally just want less government and the Libertarian Party which many here describe as 'liberaltarian.'
Exactly. I am a "small l" libertarian in the vein of Walter Williams or even Thomas Jefferson etc. In no way do I support legalized prostitution, legalized cocaine, open borders, etc. like the Libertarian Party does.
