I just gave a very real similarity. There are many others if you would like me to list them.
So you think there is no similarity between ethno-nationalism that upholds Germanic people, Anglo-Saxons and Nordic people as being superior racially, and ethno-nationalism that upholds a vaguer notion of white Europeans to be racially superior? It’s not even just that they’re similar in principle, which they clearly are, but they’re also literally derived from the same historical and intellectual traditions regarding racial science and European ethno-nationalism. Hitler is still an important figure symbolically for the vast majority of those who consider themselves to be White Nationalists, or some variation of that label. Why should I take your word over those other White Nationalists?
So despite rejecting the similarity I just outlined, you think that Marxist communism is more akin to Nazism than modern White ethno-nationalism because they may both have a vaguely similar concept of one group oppressing another (which is hardly absent from modern White Nationalism, or other political worldviews) and both use the term “socialism”, despite the fact that Hitler’s socialism was explicitly ethno-nationalistic?
I think you’re just a White Nationalist who doesn’t want to be associated with the monstrosities that the representatives of his movement unleashed on the world.
