There's zero difference between this memo and what is frequently said by people who just don't like black people (because it's too bad optics to say "I just don't like black people").
People who just don't like pakistani people spend a lot of time talking about pakistani child rape gangs. Does that mean we should ignore the pakistani child rape gangs?
serves the role of "pakistani child rape gangs"? Right now the analogy does not makes sense to me. "pakistani child rape gangs" are reprehensible, nothing that extreme comes to mind when I think of James Damore's memo or similar.
