Somehow on Facebook (I know) I've stumbled across "conversations" frequently conversed about the flat Earth notion, faked moon landings, JFK assassins, atheism vs creationism, aliens, and more ...
They don't make me grumpier, if that's even possible, but I do find it entertaining at times.
I know everything on FB has to be true as it's all fact checked by fact checkers, but at times, some things seem off to me.
