Can confirm, I'm on the Left in an oil company and luckily I don't have to talk to many people in informal situations day-to-day. It doesn't help that the company is Authoritarian, so I made a mistake talking about the sad state of the 4th Amendment here.
But, unfortunately, the irony is that the same mechanism that isolates conservatives on SV and liberals on oil companies is working here to isolate your good sense in Hacker News.
I can't believe we're suddenly having a moral crisis about business cultural politics... over the fact that a guy was fired for arguing in part that historically discriminated-against groups are underrepresented because of biological unfitness.
Political business monocultures have been a thing since forever. Dial the clock back a little and you have bosses pressuring you to campaign for Nixon. Dial it forward again and you have CEOs starting meetings with prayer. Dial it forward to today where one dude gets fired for arguing Nazi race science, and suddenly we all have to chat.
I see it more like instinct vs. reason. When reason fights instinct, the later usually wins.
We get surprised when groups that we expect to be sophisticated behave exactly like Polynesian/Amazonian tribes or chimpanzees in the Congo.
But, many times, civilization is just a varnish over bestiality, a make-up on a pig. Deep down we react like tribes that repress behavior that looks threatening to our group cohesion.
