I mean look, when you grow up in a subculture that is focused on socializing a person to hate and fear everyone and everything that strays outside of a narrow white, middle of the road, bland norm, you cut people off from learning about other human beings.
When you grow up on a diet of hate filled conspiracy theory like explanations of human beings' lives outside of your narrow part of the world, that engenders a kind of trained stupidity about people and how societies function.
