Whoopi’s big picture point is correct

“I said the Holocaust wasn't about race and was instead about man's inhumanity to man," Whoopi Goldberg said.

Goldberg is not wrong in her intended point.

I mean, of course the Holocaust is about race, but it’s just one instantiation of the human ability to do terrible things to outgroups, and sometimes those groups are defined not by race, but by gender, sexuality, class, or even vaccination status.
