I don't know why I bother, but once more into the breech.
Jewish Chosen-ess has nothing to do with religious, racial or ethnic superiority, unlike Naziism and Master Race which had everything to do with racial and ethnic superiority.
Zionists, for the most part, from its inception were not religious zealots; contrariwise they were largely what we now call "ethnic Jews";    Theodor Herzl, the founder of modern Zionism, was such a person.
Now, whether one is a believer of any religion, an athiest, or an agnostic, the concept is understandable, if one choses to learn. Or one can choose not to educate oneself, and ignorantly spout poppycock.
