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?
It's uninclusive to put one very specific brand of politics in people's face all the time with the unstated message that if you think a little differently you had better be quiet about it.
Any constructive feedback is generally received as "this person must be a closet white supremacist". Better to grit your teeth and remain silent.
