I don't allow drama on my FB page, unless it's my own.

They've adjusted it now to where you can hide an individual post without hiding everything posted by that person, or defriending entirely. I take advantage of that option a lot. For example, if something shows up on my page that is full of anger or profanity, I'll hide it without answering, I don't care who it is, or how they are related to me. I've always been told, if something offends me, to "just ignore it," and hiding the post is one way I can.
