You should consider Microsoft and Apple... employees there don't really care too much about these things
Overall, I agree with you, but it isn't that employees there don't care. It just honestly feels like the overall group of employees at Apple/MSFT is truly more diverse (not just in terms of race and such, but in terms of socioeconomic upbringing, culture, and diversity of thought), hence why they are used to being respectful of other people's views (even if they totally disagree with those) and not succumbing to the monoculture kind of thought, because it would be almost impossible to have a monoculture there in the first place.
There are definitely a few small enclaves like that at Google as well, but it feels more like a giant monoculture with some small enclaves, while I get the inverse feeling about Apple/MSFT (a giant diverse non-monoculture group, with a few small enclaves of monoculture).
Anecdotally, I have many friends working at all 3 of those (Apple/MSFT+Google), and they (independently of each other) brought up the same point when conversations got there.
Some is, especially when a company has 100,000 people. I think, perhaps, it is easy for people to forget that when some Googlers fought against the Dragonfly project, it's because they have friends and loved ones who are Chinese expats under threat from China's government (meanwhile, some Googlers are Chinese citizens). When some Googlers fought against project Maven, they were only two or three degrees of separation from people who had lost loved ones as "collateral damage" in US drone strikes during the "war on terror."
I think one of the most interesting questions is whether a 100,000 person multinational can survive without a hard "Don't question leadership" culture in a world with simultaneously this easy flow of communication and people and this much inequality and conflict.
I find odious people in general hold a wide variety of beliefs across the entire political spectrum.
