Hitler was not a communist.
Claims like this are weird.
He was a communist before he became a fascist. Once he was in power, he started making moves to confiscate businesses and property and make them the property of the government.
Do you really think that there is some hard line that separates communists and fascists, that when you are one, you won’t do the acts of the other?
Leftism always evolves towards total ownership by those in power. This is without exception.
