"on the right side of history" This phrase has always confused me. Unless you are a prophet or time traveler, how do you know you are on the "right side" of history until a significant enough time has passed? And what does "right side" even mean? Is this about winners and losers? Was Stalin on the right side of history since he was a winner (in a manner of speaking) while Hitler was on the wrong side of history since he was a loser? Or is this some kind of moral/ethical rightness? But how do we know what will be moral/ethical at a point in the future that our time is considered to be history? 100 years ago I'm pretty sure the average person wouldn't have considered someone who supported gay rights to be on the right side of history. Again, until enough time has passed, how can you know that you are/were on the right side of history? It sounds like wishful thinking to me.
