It's really amazing how different people's experiences with Facebook are. I have been on Facebook since it started (I was at one of the original schools, I was in that famous first million users).
My feed is entirely photos of friends' kids, invitations to local events (things I actually attend), folk-dancing groups I'm involved with, and the like. I have literally never, not once, not ever, seen any rage-bait or political content (other than that directly written by friends - not reposted) in my feed.
