Yep, those "angular" features are spread throughout the population of human beings, no matter their skin color. So are all facial features. A racist frame, claiming that one type of features is the best and that those features are white because of course they're white since they're the best, makes it impossible to see the world as it really is.

Bella's acquaintance with reality is shaky at best. I wonder if it's rooted in her racism and sexism. She was brought up to believe certain things are always and forever true of groups of people, and that some groups are inherently better than others. To keep believing that, she'd have to ignore the real world -- and how do you ignore such a huge part of the world without ignoring the rest of it? No wonder she can't relate to people.
