This is such poor logic. Being around when something happens doesn't mean you somehow know a vast amount about that something. People later can study that something and known much more about it than people who were living during those times.

Ask the average American who was alive during the Cold War what the effects of it were on America and its population, they'll say some generic shit they heard mouthed to them by politicians. Ask any 21 year old college student who just finished a course on the Cold War and its effects on America, and they'll have much deeper understanding.

Being old and alive during something doesn't make you knowledgeable about that something than someone younger and educated. You'd know this if you weren't all idiots, but so many of you are dumbass motherfuckers.
