In normal conversation, I would ask you to quote a Gadol who claims that there is some Jewish goal of a political state (chas v’shalom), but my sens is that you will dodge even that simple request because otherwise you could have simply done it in your last response. If I pushed you, you would probably quote the known kofer who “kasherd” the zionist movement that Rav Elchonon Wasserman ztz”l said clearly is a “rasha gamur”.
You are correct that our Holy Torah is guilty of the “no true scotsman” angle as the Torah is our starting point of what is true. Anything that is not Torah is not true and anyone who breaks away from our mesora is a kofer and certainly not a “Gadol b’Yisroel”.
Regarding zionism today, nothing has changed. Anyone who hates arab terrorists more than IDF leaders is guilty of the heresy of zionism. The Torah teaches that we must hate rashayim with “tachlis ha’sina”, and this is true for anyone who is mechalel shabbos befarhesiyah including a tinok sh’nishaba. Framing kefira as a “specific strand of a specific ideology” is just another mental trick to join ranks with those who want to rebel against Hashem and His Torah.
