“Calling large factions of Yere Shamayim, Torah keeping Jews fools/idoloters is not a wise choice of words.”
You have it backwards. The facts are what they are. As Rav Elchonon and all the rest wrote, Zionism is idolatry and heresy, and “Religious Zionism” is both religion and idolatry biShituf. And idolatry is, of course, irrational. So, anyone who believes in Zionism as part of their religion (as do “MO” and other “Religious Zionists”) is, therefore, one or both of those: fool and/or idolater. It really is that simple.
So, therefore, you have it backwards. Those large factions of Jews should give up the idol of Zionism. By doing so, they will cease to be both fools and/or idolaters, as noted.
