I find that just muting anyone who has anything to do with politics on facebook works well for me. I go on facebook to see your cutesy images and how your life is going not for long political diatribes.
For some short time, that worked for me, until facebook noticed that I was spending less time on it. Then, they started to push posts from other politics-related accounts (especially from ones at the side of the spectrum I used to antagonize most with). That was 4 years ago. I left that crap and didn't look back.
