Silly filmmaker! Aren’t you up to date on the current SJW narrative?
The so-called “Holocaust” is just as fake as the so-called “Armenian Genocide”. Besides, there are no actual, bona-fide “Jews” in the modern world anyway! They all converted to Islam and became Palestinians. All the so-called “Jews” are AshkeNAZI Khazar impostors from Central Asia!

Nazi racial ideology was built in no small part on the (bogus) work of Hans Gunther. Gunther asserted that "Arminoids" originated in the Caucasus and spread into both Eastern Europe and Mesopotamia, which would mean that European Jews and Israelites were the same people -- again, that racial requirement to being a "Bona Fide Jew". Gunther also held that Iranians were from the same pool as Jews-- ironic considering that in reality Persians are genetically much closer to "Aryan purity" than any Northern European subgroup. But hey, they have "short heads," so they must be some kind of Jews.
Rather than squabble about racial nonsense, I think it suffices to say that millions upon millions of people were murdered by the Nazis, and nearly half of those people were Jews. Whether they were Chasidic or not is kind of besides the point.
