Yeah thing is, the guy’s memo is not Racist, or Sexist, or “anti-diversity.” That’s what you’ve been told. Nor is the author a Racist or Sexist who needs to be kicked out of Google, or society, for all the wrongthink you’ve ascribed to him.
What the memo actually was, is…well. Here it is:
https://assets.documentcloud.org/documents/3914586/Googles-Ideological-Echo-Chamber.pdf
Written by a Harvard educated Biologist, sourced, that contains a handful of scientific observations, but mostly a description of a pernicious environment where some speech, even if true, even if an important and closely-held opinion, is met with censure and slander. That’s what you’re participating in.
Here’s some scientists backing the social and biological components of the memo:

So a larger question is, the question everyone should ask themselves before going off on one of these things where they start slinging accusations of racism and sexism around willy-nilly, without seeming to care about the real impact such accusations have on the lives of others is:
What if you’re wrong? Because you are, you should know. You’re on the wrong side of science, but perhaps even more importantly, you’re on the wrong side of the Principle of Charity, and you’re on the wrong side of Western enlightenment values of Expression and Idea Exchange. If the person you’re talking about isn’t actually a bad person, and you’re participating in harm to that person, what does that make you?
