'Authoritarianism' is a bullshit vague idealist concept that can't be linearized into 'more than', 'less than', 'most' or 'least', and make any sense.

The USA throw people in prison for decades and enslave them for being a victim of the drug trade. They have one of the largest proportions of imprisoned population in the world.

They also allow socialists to own guns and propagandize, to a larger degree than most countries.

Liberalism is complex, contradictory and idealist, so terms like 'authoritarianism' are basically meaningless to apply to the real world.
