You know, I actually sympathize with the opinion that people should be expected and assumed to be able to resist attempts to convince them of being nazis.
The problem with it is, it already happened at least once. We know how it happened. Unchecked narratives about minorities or foreigners is a significant part of why the 20th century happened to Europe, and it’s a significant part of why colonialism and slavery happened to other places.
What solution do you propose?
Studying history better would be a good start. The Nazis came to power because they were a far left party and the population in that era thought socialism was a great idea. Hitler himself remarked many times that his movement was left wing and socialist. I expect that if you asked the LLM trained on pre-1940s text, it would have no difficulty in explaining that.
By studying history better, people wouldn't draw the wrong conclusions about what caused it. Watch out for left wing radicals promoting socialism-with-genetic-characteristics.
