This, along with all the other comparisons involving other non-white people, makes me think - perhaps racists suffer from a deformity in the brain and eyes that makes them see reality in a distorted way.
They look in a mirror and see a perfect "aryan", they see a black person and literally see a distorted view of them, and they see a photo of an asian woman grinning and see ... that.
They can only see caricatures, except for people who look like them. And their perception of reality is so heavily influenced by perception that they even see other white people as deformed just because they don't share their values.
Perhaps they're just a bunch of idiots who have repeated racist jokes so much that they stopped being jokes.
