While the right could be authoritarian, in most cases it isnt, it focuses on self-discipline and self-governance.
The left is always authoritarian, anarchists in the 1800 turned into bolshevist-marxists by 1900. You have to force equality because it is unnatural, and naturally people are unequal.
So you're saying Mussolini wasn't a right-wing authoritarian? Or that the Liberal left Dutch society is authoritarian? The Dutch culture is quite similar to what Libertarianism promises (and has not had a chance to deliver so far)
