It’s always entertaining to meet people who think they know everything, and also think they can predict the future - and refer to that mindset as being “realistic”!
Who said anything about knowing everything? Judging the likely future actions of people based on their past behavior isn’t predicting the future. It’s common sense. You are the one with wishful thinking, as if the same kind of people who got us into this mess are going to suddenly change and become James Madison or George Washington.
