IBM punchcard system proves the holocaust

[borjastick]

I am looking for a simple explanation and background to the claim that the holocaust happening was proved due to the Germans using an IBM punch card system to record data etc.

I recall some mentions a long time back about IBM and punch cards but would like a for-and-against for this claim please.

Can anyone please oblige?

They didn't claim that the Holocaust happening was proved due to the Germans using an IBM punch card system to record data etc. They claimed that the Germans using an IBM punch card system "help[ed] automate the genocide of Europe's Jews," as Sam Jaffe once put it in Businessweek. As usually, Holohoaxers used, in this case, their dear double trick of an a priori conclusion (which can be summarized as follows : The Holocaust is a real event. Period.) and a much-widened definition of the Holocaust (meaning anything bad that happened to some Jews in Europe and North Africa before and during WW2) to fool their credulous audience.

I don't see any substance to this idea. Whoever believes it should articulate their case.

As I understand it, these IBM punchcards are just computerized versions of paper documents, so whatever proof is alleged to exist should exist also on paper.

Some activists have gone after IBM for selling punchcard systems to the Nazis because those punchcards were used to register Jews. However, the U.S. also implemented a punchcard system for its interned Japanese-Americans, and that also involved IBM. What's the difference?
