And would you agree the America Libertarian / conservative is the antithesis of authoritarian central planning?
Yes, by and large.
But the further you go towards extremism, the more right wing ideologies require authorities to enforce their will, maintain order and implement policy.
While right wing parties might remove some bureaucracy in economic management - it often appears as social management and policing.
The key to understanding this is to understand the ideological principles ALL right wing parties share - namely support for the upper class, the use of capital and a kind of 'social homogeneity'.
