It's all quite surreal, isn't it? At least people seem to be waking up. Bravo to HN for keeping up the coverage and not letting these outrageous revelations fade to a whimper.
For me, it reifies all I learned Nth hand about things like The Big Lie. Growing up and studying WWII history I had to accept that it worked, but I never really understood how until ... hmmm, went to college in 1979, read/skimmed the Boston Globe that my student group had a subscription to and e.g. saw how much it lied through omission. The 21st Century has taken this to the Nth degree in the US.
That was when I switched to really detailed study of the Protracted Conflict (the Bolsheviks vs. the world) and it was e.g. easy to understand what the big deal about revolutionary truth vs. bourgeois truth was about.
