Mein Kampf, along with Das Kapital, essentially defines identity politics. Very readable and educational, and I see its premises and paradigms practiced in modern collective identity movements.
Marx and Hitler were wrong about many things, but were also very perceptive in ways that modern westerners are ignorant.
I wouldn't consider myself a communist or fascist, but those ideologies appeal to many people for normal reasons, and I hope we might understand it before it's too late to effectively resist.
Edit: The Chinese Communist Party is essentially a Nazi Party that believes in Han supremacy. Islam amounts to Arabic supremacy.
"Historical Rights" are tenuous, as anyone familiar with medieval history will know.
