I'm not OP but I am politically engaged with not 100% the same opinions, so sometimes I get annoyed by the environment and have to remind myself not to care.
Imagine your workspace was full of aggressive pro-Trump messaging. A bit distracting maybe?
But I don’t understand how a workspace that was full of any kind of aggressive messaging is healthy even if I agree with it? That sounds pretty toxic to begin with.
Imagine also your coworkers casually mention they'd gladly shoot any pinko commie liberal they'd encounter, good that there are no such people among us! And then discuss how liberals are filthy amoral idiots only worthy of being spit on. And you happen to be a liberal. And even though you know they're probably joking, and they most certainly don't mean you, would it influence your work relationship with those people a little? Would it make you more distracted and less motivated?
And what if they get their suspicions - say, you couldn't bring yourself to praise Trump as much as others - and then your promotion, which one of your Trump-loving managers has a decisive voice on, does not come through, would you wonder why? Would it impact your work? I think it might.
And yet, I've heard things like these (not about Trump, it was even back when Trump was a TV personality) from many people. Did it impact my work quality? I really hope not, as much as I can help it. But I certainly didn't enjoy it.
