A neat psychological trick our brain loves is that when you have a "fallback" plan, it puts immensely less effort into the primary one. Because you are assured success, you don't need to stress as hard about making it work. And vice versa if you don't have one.

Point being, Jews have guaranteed citizenship to a nation of such immense power and influence means they don't need to put in half the effort into helping or maintaining any host nation. When shit goes down, they are still protected. So reflexively, they are less "X-ican" than anyone else in the nation because of aforementioned trick. Same with Illegals and Jeets don't care nearly as much about their host either.

And to quote a classic anti-feminist maxim, its never a question of if that will but that they can. So even those who don't pledge, or even speak against it, are still less trustworthy because at any moment they can reverse course and take full advantage with minimal loss.
