I wish the worst thing about politics for me was how noisy it is. I suspect that the people who are bothered by the noise of politics are usually people who have usually never had legislation or policies introduced which can directly or indirectly get them killed.
Politics is usually at the forefront of my mind, as with many others who feel lives are at stake. As such, I think the only way to truly stop politics from being a common topic is to put fewer people in danger to begin with. I don't see that happening anytime soon.
There's also the problem of bots and paid commentary though, which is a popular way to influence social groups. But that's just the same problem as humanity has always had and are always going to have - verifying who is real and who isn't. This is a problem which will also get harder to detect and measure with further developments in machine learning. Realistically we would need some ability to authenticate a user's actual singular identity, which requires collecting and storing more personal user data. Even then, to do this with maybe sufficient accuracy would prevent many people from being able to participate. It's a huge can of worms.
So I'm afraid you will have to stick with the current hacky workaround of blocking or ignoring people and communities who discuss things which don't interest you. Much like how I have scrolled past many pictures of beans today. And you can join communities which share your definitions of politics and distaste for its pervasiveness.
