Yes, and the fact that we use the term "Hitler" and "Nazi" with little to no discretion. The terms are virtually meaningless now. So many people in my social circle used these words to describe Luckey, yet I do not see Luckey participating in genocide.
Is it fair to reduce Hitler and the Nazis to just the mass genocides they perpetrated? You talk about the terms becoming meaningless, yet that was the the only thing they did.
For many years they were campaigning to make Germany great again, as other countries were taking advantage of them and some elements in their country were intentionally making bad deals. Plus obviously the people who weren't real Germans were a problem that needed to be dealt with. They wanted to build up the army and built strong links between large corporations and the government.
So maybe it's okay to call people who do things like that Nazis?
