Also some Christians believe the rapture will only come after Israel is back in the hands of the Jews. Since it hasn't happened already, they might think that it has to be completely in the hands of the Jews. It might be about Jerusalem instead of all of Israel.

So they can still hate them while wanting them to fulfill their "prophecy". Once they control whatever land some Bible contributor says they need to control, then God will punish them while rewarding all the good white folks in a way that lets them skip the whole scary dying thing.

Not sure if this specific asshole subscribes to that belief, it might just be normal Nazism (the Nazis wanted to send the Jews to Madagascar before understanding that you can't just send a large group of people to some other location without some kind of military conquest, which is part of why they called the Holocaust the "final solution").
