Would you also claim that “it is assur to say lashon hara about ‘Jews for J’ evangelicals even if they [mistakenly] believe that the state is the forerunner of our ge’oula.”?
Would you say that this statement was also the intent of the Steipler Geon zy”a?
Of course, it was not.
The kefira of the false religion called “dati leumi” is not the simple mistake of “aschuleh d’geila”.
The Steipler says very clearly that an otherwise frum yid does not cross the threshold of kofer in ikkarei hadaas if he makes the mistake of “aschuleh d’geila” vis-a-vis the false geila of the tziyonim. That doesn’t mean that everyone who indeed makes that foolish mistake now has a free pass to believe all types of kefira and apikorsus and can never become a rushe!
Is this nonsense your claim? Or is there some other reason you distort the words of the Steipler Geon?
