DerechErets is right on.
yichusdik, you are, surely unwittingly, promoting a different theology, known as “Religious Zionism” which in Rav Elchonon Wasserman’s words, is Torah and Avoda Zara mixed together.
It is the Zionists who have literally “redefined Judaism and Jewish observance to the point where you have produced a new religion”.
To answer your question, I would go with an approach like Eliyahu haNavi’s “Ad Masai Atem Pochasim al shitei HaSiifim” question.
If the Avoda Zara of Nationalism/Zionism is your faith, then simply say so. But if, instead, the Torah we received from Hashem at Har Sinai is your guide, then “hasiru es elohei haNeichar asher bisochichem” and join the Jews who remain loyal to the Torah and have been zoche to see past the bitter lies of Zionism.
