The word you're looking for is "nationalist", not "authoritarian". Authoritarianism is when you're commanded to do the stuff you quoted. Nationalism is when you do it of your free will or out of peer pressure from others who do it of their free will.

Nationalism is more insidious than authoritarianism. When you have an authoritarian government, you have an enemy you can clearly identify and the resistance feels morally justified. Resisting nationalism often elicits negative reactions, such as branding you as "unpatriotic" and such.
