One cannot, even if there are decades between them, kill millions of jews. So you can bring millions of their worst enemies in the place. I know someone in germany who took a young syrian and after four days said, the greatest thing germany invented was the holocost holy shit. He's using a minority group to stigmatize another one. It is a magic trick, rhetorically speaking, to be like, what if people who support people of other races? Yes, are the real notses.
