Great-grandfather was an agronomist and no-nonsense man; when some higher-ups wanted him to say a bunch of ridiculous lies for propaganda, he refused.
This didn't helped anibody (yes-man are easy to find) but, obviously, ruined his career: he didn't care.

My grandfather, died some years ago as a fascist, "forgetting" what happened to his own family.

That's why I'm not surprised that people ignores recent history, especially things that didn't happened directly to them.
