There are a couple of interesting observations to be made if you carefully consider exactly what he was saying. Like most people I'm sure, I read the headline as, "Only a million people were killed in the Holocaust, not six million." But no, he's not saying that at all:

At least five million of the six million were “total goyim,” Mizrachi told the crowd....

See, the magical, mystical "six million" were killed, to be sure, but he's only pointing out that most were not Jews by Jewish law. Taking his claim as presented, that brings up two important points, neither of which were discussed by the rabbi or anyone the Times of Israel cared to talk to. (They should have talked to me.)

First, did this rabbi nor anyone else care to speculate on why the Nazis would kill five million fellow goyim? Were they just randos? The first five million to walk past empty boxcars? Were there that many Freemasons and gypsies walking around Germany at the time?

Second, well... what about them? No one in the article seems to care in the least that, still, six million people were killed (sic) however you care to divide it up. Five million living beings literally bear no mention whatsoever.

So when you wrap it all back around, maybe that first impression really was correct, at least according to these Hebraics: "Only a million people were killed in the Holocaust, not six million." Get it?

(And see why they didn't talk to me?)
