Tip to surviving Facebook: If you must go through your feed, immediately start "hiding" toxic/hateful individuals that post nothing but bad content. If an individual only sometimes does so, start hiding their sources. E.g. If you see some friend that happens to post bad stuff from CNN or Breitbart and the content from that source upsets you but you want to see that friend's other content, then hide the page they're "sharing" from.

Most of the time, people don't post original links/content, so it's a "share" from an existing page that you can hide.
