I think if you are active in communities related to news and politics you're going to see political and news related posts. It's kind of a part of the deal.
It's kind of a big part of politics. It isnt politics if it isn't involved enough to contend with propaganda and extremism. That'd mostly just be entertainment, like your typical late night TV coverage of news and politics.
You have to be able to parse through false information. That is what is part of politics.
Like, a lot of bullshit is thrown around in political spheres. There has to be some level of expectation that you will have to deal with that bullshit.
