No.
Those who deny or minimize the Holocaust are the type of people who probably couldn't pick out Germany, Poland, Czechoslovakia, Yugoslavia, the Ukraine, the Benelux countries, or Norway on a map. For these people, history started around 1970, and they were either never taught or bothered to learn any history prior to that time.
Would say those who deny/minimize the Holocaust are the type of people who would deny my namesake's GULAG system ever existed, or that the Holodomor ever happened. But it's funny, have never heard of anyone denying the GULAG or the Holodomor. And IRL have never heard anyone deny the Holocaust happened, only on anonymous message boards.
In general, believe the intelligence level of the average KFer is rather higher than most people IRL. So when I see Holocaust denial/minimization, in the face of the overwhelming amount of history, from many countries, and from many sources proving the Holocaust happened, I am very surprised and disappointed. Make the effort. Read the history. Watch the YouTube videos from the liberation of the camps. Gonna tell Ike it didn't happen? Patton? Omar Bradley? They'd laugh in your face, if they were around.
That's all I need to say on the subject.
