There's two axes of politics:
Conservative/Revolutionary (sorry, Liberal or for Europeans:leftist) defines values
Anarchist/Authoritarian defines methods.
Libertarians are anarchist conservatives
Nazis are authoritarian conservatives
Communists are authoritarian Revolutionaries
Democrats are moderate Revolutionaries
European Conservatives are moderate Conservatives
American conservatives are moderate tending toward anarchist conservatives.
Now there's convergence, as we're seeing that Joe American will not listen to reason, but will do whatever he can get away with, and that anarchist/libertarian methods therefore FAIL. We're also seeing that socialism, as a basis of government, encourages tyranny.
