It is counterintuitive but it does make sense. You see the initial plan the Nazis used to try to get rid of the Jews was to expel them from Germany. They had no problem if the Jews all grouped together and settled their own country so long as it was somewhere else. Far away from them. (And when they didn't leave they made conditions horrible for them). That's why antisemites love Zionism; it's a way to get rid of the Jewish population in their country without dirtying their hands with ethnic cleansing. Which is how we get to conspiracy nutjobs who rant about Jewish space lasers setting forest fires in the US for some reason, turning around and enthusiastically supporting Israel and defence aid for Israel.
