Debunking Holocaust Denial - Denier Argument #1: No Jewish population decrease?

On July 16, 2008, infamous Holocaust denier David Irving held a meeting in New York with some of his supporters and fellow Holocaust deniers.

Some individuals who were not Holocaust deniers came to document the meeting and ask questions. During the meeting, an un-named Holocaust denier approaches one of the interviewers and says:

"How could 6 Million Jews be murdered in gas chambers, and not be a decrease in the world's Jewish population?"

This is a common argument used by Holocaust deniers to try and claim that the Holocaust didn't happen. However, there is one crucial flaw in this argument: It is completely false. There was a massive decrease in the Jewish population during and after the Holocaust, and this is just one part of the mountains of evidence that the Holocaust happened.

As you can see right here, there was a massive decrease in the global Jewish population from 1939-45. This was due to the Holocaust. Deniers lied once again.
