Lovely notion, but a delusion.
The BLM backed down in NV because they didn't want to look bad.
The Nazis, at least after the war started, couldn't have cared less if they looked bad. Armed resistance against them would simply have resulted in their bringing in additional forces to crush the "revolt."
That doesn't mean that such resistance isn't sometimes the right and moral thing to do, but a few civilians could not have taken on the Wehrmacht and SS and survived, much less won.
One can (sometimes) hit and run successfully in such situations. One simply cannot stand and fight. Unless you want to die. And probably your whole family, the neighbors, etc.
"We the people." Another problem in Germany was that "we the people" supported Hitler. It's generally conceded that by 38/39 he had somewhere between 80% and 90% of the German people behind him, possibly even over 90%.

To your points. 80-90%. That was the Nationalism part. In Nazi Germany, we the people couldn’t fight. They took the guns.
