I believe what I believe because that’s what I believe. I don’t have a problem with what other people believe as long as they don’t try to tell me what I need to believe. That part has been hard for some, especially my mother.
Again if Facebook, Fakebook, Farcebook, or whatever has been or is a problem for you then you are doing it wrong. But I have zero issues with unfriending people. Friends, family, doesn’t matter. It’s my feed and I like it clean and pleasant. Not much drama at all and when there is a dust up I just roll on by.
