I 100% don't ever want to hear my co-worker's opinions on politics (even if I agree with them). I work to make a living and survive. Activism can happen outside that framework, otherwise people will be forced to endure it under the threat of losing their livelihood.
It's a distraction at best and a massive disruption to the business and people's personal lives at worst. Look at Google. People are threatening each other, stalking each other, slamming each other in the media... Google created an environment that promoted a particular brand of politics and this is how it ended up. A company that promoted right wing politics would be just as bad.
If you don't like a government policy, take it up with the government not your place of work. It's only fair to your co-workers.
