Far worse. They're Lubavitchers - apocalyptic Jewish supremacists.
They believe that if they can bring about the apocalypse then their god will appear and give all the Earth to the Jews, to rule over the surviving goyim like neo-Pharaoh gods.
It doesn't matter if such an idea is insane. What matters is the Lubavitchers like Kushner and Trump believe it, and are working to bring about their coveted apocalypse.
