After US's controversial election season, a workmate and friend started blaring conspiracy theories and criticizing the government over company chat in one of the channels. The occasional conversation is fine, I'm open to idea sharing. But I think it has reached the point that it has become distracting and at the same time awkward. I've worked with this person for years, but only recently did they start doing this.
I'd find myself or someone else defusing the conversation by switching topics. But they're persistent, coming back moments later with more. They would post articles and videos on company chat, urging us to read/watch. They'd ask awkward questions like ethnicity, race, origins, political views, sides taken. They even mention that we'll come over to their side someday. It's also useless to argue, as they sound the type that's committed to their beliefs and would refuse views other than their own. HR may also be on the same train, as they once posted a photo also over company chat that implicitly showed the side they're on.
I'm in an awkward spot, and probably other people are too. Everyone has their opinions, but doing it this way seems very unprofessional. I believe there are unspoken rules in the workplace, and they're breaking some of them.
