If a Facebook friend (in this case also a friend in real life) posts an article or link about a story that has been proven to be false, would you call them on it? If so, in public so others can see? Or via pm?
This happens over and over and over with this same friend. We are on opposite sides of the political divide, so it almost feels like if I do say something, I'm "challenging" their beliefs or views.
In this particular case, I've decided to do nothing. But I'm just curious as to how others deal with issues like this.
