You’re the most annoyingly obtuse person I’ve ever encountered. There’s no specific physical type that causes people to instantly say “That’s a Nazi.” No one is going around beating up or murdering random blonde-haired, blue-eyed people or even people with shaved heads.
They are however killing, beating and harassing people who “look Muslim” even if they are Christian, Hindu or Sikh. This isn’t just a random thing that happened once. Sikh’s especially deal with it constantly.
This shouldn’t be hard for an intellectual like yourself to understand.
