Point taken, though, about holocaust denial and fundamentalism. It's not without reason that both creationism and holocaust denial are chapters in Michael Shermer's "Why People Believe Weird Things", a study of why people come to hold positions supported by no evidence.
Other facts that a person should know (off the top of my head): -The Great War 1914-1919 -Otto Van Bismark -WW2 1939-1945 -Pearl Harbor Dec. 7, 1941 -D-day...Normandy Beach...Hitler got fooled big time... thought main landing was in Greece -Fat Man (plutonium) and Little Boy (uranium) -etc.
