I know nothing better than for any company to be mission focused. You go to work to do work. And you do so with a degree of neutrality, as you can't pick your colleagues, yet still need to cooperate with them.
This doesn't mean you can't say anything at all, it means you shouldn't be overly divisive or confrontational. A company isn't your personal Twitter playground.
If you do have something political to say, a grave social justice error in the company's policy for example, you can still be reasonable about it. To mention it respectfully and proportional to the issue, rather than going nuclear.
I work in a tech hub in Europe that has 80 nationalities, people from all walks of life. Any ethnicity, sex, gender, sexuality, religion and political conviction you can think of and we all get along just fine with zero tensions.
It's a joy actually, to work with people wildly different from yourself, whom you normally might not meet if it wasn't for work. We don't even have rules on politics, because they're not needed. Nobody brings politics or activism to work.
This brand of aggressive identity-based political activism really is a manifestation of the deplorable state of US politics. It's really quite rich to take home 200K a year and feel oppressed. Such a thing is only possible in the US, the rest of the world laughs at you.
