I just started unfollowing (for people I actually interact with, or might need to) or unfriending (for people I will never see again, and don't want to) people who post overly political bullshit.

I don't mind a bit of politics, Australia is going to hell in a handcart and the least people can do is raise awareness. But I don't like inflammatory (and often completely fake) bullshit.

I can now scroll my newsfeed (which I don't actually do that often) without getting high blood pressure.
