National socialism enthrones the traditional values of the people as the basis for its morality and rule of law. Adherence to whatever spirituality is traditional in the nation is valued.

Communism reneges and destroys any traditions, values or morality in favor of POWER and only power. Any form of spirituality is scorned and prohibited.

Isn't that literally the same thing except for which culture holds the power?

The difference as far as I can tell is that they're both copes, trying to dismiss the gruesome nature of this existence. What you call "National Socialism" attempts to cope by pretending, absurdly, that all the evil and cruelty of nature is good. Communism copes by denying that such things are natural, and saying they only exist because of orange man or something. The former was the order of all major civilizations for a very long time. Communism is like a 2.0, because it's even worse. Communism also mandates its rule and silences and tortures all opposition and dissent. But it also opposes the natural order, but at the same time it can't truly get rid of it, only pretend like it doesn't exist; so both the communist regime and nature end up oppressing everyone at the same time.

The truth no one ever wants to admit is that the world itself is evil, fundamentally from nature and even the laws of physics. The archons work hard to ensure that most people love the world and life in it even though it enslaves them. That way it's easy to convince them to keep coming back.
