I've often said that totalitarianism and authoritarianism are fully in line with the history and ideals of the USA. The reason Americans don't see this is because of certain other history and ideals of the USA. The history of propaganda and brainwashing.
The USA is an Orwellian nation so just about every single word in Americans' political vocabulary has been twisted and redefined in a way that makes the USA look better. Political words, as Americans know them, are out of line with their meanings as understood by the rest of the human species. They are useless for meaningful communication and only serve to glorify the USA.
So for instance, in the English language 'authoritarianism' means obedience to others' will. In the American language it means something quite different. It means collectivism. Thus, private property which is everywhere regarded as a deeply authoritarian and indeed totalitarian concept, doesn't raise an eyebrow in the USA. Meanwhile, collective endeavours like single-payer healthcare or mass transit or firearms regulations are regarded as "authoritarian" in the USA.
Going on, freedom (redefined as power), democracy (plutocracy), patriotism (fascism), liberty (egotism), free speech (apathy), human rights (civil rights). That last is an interesting one. As everyone should know, and a few people do know, the USA is one of a very small number of nations on this planet that refuses to even so much as recognize human rights. Americans buy into an obsolete and discredited 17th century theory of "natural" rights which none of the rest of the world believes. So-called "natural" rights are gibberish whose "justification" is a primitive State of Nature (ie, anti-civilization).
Furthermore, the American word "liberal" has no analoguous word in the English language. Everywhere else, classical liberals, neo-liberals, and just plain old liberals are right-wingers. Liberalism is an inherently right-wing ideology. As a result, American "liberalism" corresponds to no word in the real political landscape ... except for the term anti-fascism. So if Americans spoke English they would have to admit that their country has been on the brink of fascism continuously for many decades.
Another good example is the USA's being the only country hypocritical enough to use "free speech" as a code word for "end of conversation". How many times do people ritualistically say "I disagree with what you say but will defend with my life your right to say it" when they really mean "I don't give a fuck about what you say, it's never going to change my mind"?
The USA's attitude towards human rights far surpasses hypocrisy. It's a blank stare of non-recognition. Americans don't even comprehend the notion of universal human rights. And when they are told the human rights, they object that "those things aren't human rights!"
The Americans' use of NewSpeak instead of English is itself evidence of a deeply authoritarian culture. Admittedly, it's impossible to say this within NewSpeak errr American so we have to use English! So in the English language, it is fair to say that the USA is a deeply authoritarian culture and has been so since the Great Awakenings which have turned Americans into a nation of total control freaks. The current fad towards overt despotism was begun more than a century ago, not a few decades.
