I think this here is the point where the author would disagree. Google employees and the staff at many larger tech companies produces their fair share of drama on virtually any political topic, and that's what makes this more off-putting.
I'm not black but I come from a fairly poor background, and in the tech field obviously that is rather the exception than the norm and I've noticed a similar thing when it comes to class issues.
You have people who start political mailing lists on gender pronouns and technicalities that nobody on the street has ever thought about, but then that same person talks about homeless people in front of the office with a sort of callousness and elitism that is pretty breathtaking.
If we were just talking about your random corporate culture where everybody just sips their coffee and comments on nothing then in a way that'd make these things much less noticeable. But when you have workforces that are hyper-vigilant and politically correct show disregard on topics that touch a really wide population, like the African American community in the US in this case, that makes for a stark contrast.
