Hakatan- “That the flag is not A”Z doesn’t make Zionism itself any less idolatrous.”
Forgive me, but yes it does!! In that teshuvah, Rav Moshe clearly calls the tziyonim reshaim (as opposed to ovdei a”z), but just as clearly says the flag isn’t an object of a”z. If he really felt zionism was a”z, then the key symbol and object of zionism, the Israeli flag, should be considered an object of a”z, just like the Xtian cross, is an object of a”z. Would you daven in a shul with a cross? No! Then why would you daven in a shul with an Israeli flag, unless you believed it was *not* the object of an idolatrous movement?
