You are conflating what I said beyond any sane proportion to compare it to claiming to know what it was like to go to war based on watching a video. That's just being silly.
I said, "a little of what the time and people were like back then." And if you watch a bunch of interviews of Hunt, for instance, I maintain you will indeed grasp at least a little of what the man was like. Certainly enough to know that his bearing has little resemblance to that shown in Rush.
The same goes for what life was like. Will you have a fully realised, textured and nuanced comprehension of what it was like? Of course not. Will you grasp "a little" of what it was like? Yes.
P.S. I was born in 1973 so I was in fact alive for most of the 70s.
