FYI, https://www.washingtonpost.com/news/morning-mix/wp/2016/10/04/poor-gorilla-teachers-aide-fired-for-racist-facebook-posts-about-michelle-obama/ Some people don't seem to get it. The gorilla jokes are no longer funny! Actually, they have never been funny!
I have a simple rule; I don't put anything on social media (all I have are Facebook & LinkedIn) that I would care if it landed on the front page of the local broadsheet.
It's too bad that people have careers ruined over these types of things, but people have to start realizing that Facebook isn't QUITE the best place for them to air their most intimate thoughts, especially when there are racist or other types of undertones associated with them!
