ELI5:  Why did Hitler think blonde-haired blue-eyed people were genetically dominant when he had neither of those traits?
gpt
He thought *Aryans* were genetically dominant. The stereotypical Aryan was blonde-haired and blue-eyed, but that's just like the stereotypical Japanese person having straight jet-black hair; few people thought that you had to look like the stereotype to be Asian.

In general, the Nazi beliefs about race weren't nearly as extreme as people like to think. They *acted* on their beliefs in extreme ways, but the belief in white northern European supremacy was pretty widespread among white northern Europeans, and the Nazi version wasn't all that much different.
