Cutting off a Facebook friendship is likely easier than a non-virtual friendship breakup. It doesn't require confrontation and you probably wouldn't do it to someone you see every day. Academics have looked into the top reasons for unfriending a person. The number one reason: repetitive posts. One researcher explained: "The 100th post about your favorite band is no longer interesting." Word. The second most-popular reason: controversial posts about religion or politics. And coming in third: racists or crude comments.
If someone hasn't completely offended you, you might consider softer options: hiding them from your feed or upping your privacy settings for specific people who can't help but share inappropriate stuff on your wall. Maybe this has happened to you. Have you ever gone to someone's page and realized you suddenly can't see tagged photos or write on the wall? Go ahead and chalk it up to responsible privacy settings, but it'll still bruise your ego a bit.
