I wasn't aware that only universally held views were appropriate to share but even if that were so, how can one even know what is or isn't shared unless one or the other speaks first?

It's funny, because if were is a ban on sharing unshared views, we could never hold any views at all!

Then perhaps you've never had an unpopular opinion or view on an emotionally strong topic.

> but because your coworkers won’t share your views on all of your emotional outbursts

in a democratic society that's to be expected and a good thing, I'm not exactly sure why anyone would have a discussion if they already share their views.

Here in Germany politics is generally present in workplaces and nobody finds that odd because it's not like the place where you spend half of your day ought to be a civil society free zone. Covid workplace mandates and rules were highly contentious, where else is a better place to discuss them than at work, where they matter?

You are assuming that people are willing to discuss issues in good faith. That is certainly not always the case - being on the wrong side of the line means getting publicly shamed, insulted, and your career path ended. This happened to a friend of mine who merely suggested that discussions on abortion happen in a chat channel other than the main engineering one.

Unlike religion or race, there are no legal protections for political views. If you disagree with your boss, you're risking yourself. If you agree with your boss, you might be alienating a future boss. There's no winning.
