Tragically, it's become fashionable and encouraged for politics to seep into every facet of peoples' lives thanks to intersectionality and aggressive behavior from the woke crowd. Without a firm no-tolerance politics policy from the employer this kind of stuff is just going to continue. However, any organization that publicly declares it won't accept political discussions in the workplace is probably going to receive the full brunt of outrage from the activists. So sadly, you probably won't find any company that openly advertises it's neutrality.

You may have some luck with small companies, if only because there are so much fewer potential activists working there. Avoid large multinationals like the plague.

Any company that hires a lot of young people / entry level developers is going to have way more of the activist types. Especially if they're right out of university. You could try searching for positions that use older tech-stacks. That's one roundabout way to find and older, less engaged, crowd.

As an additional word of caution, the people you encountered sound like true zealots. I'm not being hyperbolic, I truly think many of the woke crowd are modern-day proselytizers. Be very careful disagreeing or being critical of their views.
