zahavasdad: A correction: The munkatcher rebbe did not have a son. He had an only daughter who married R”boruchel Rabinovitch, who succeeded him. And, correctly, he changed his mind,becoming the Rov of Chulon and a candidate for israeli Chief rabbi. The grandson, however, is still anti -zionist,although in much lesser degree than his grandfather.
DaasYochid: I don’t think that this dispute about sholosh shevuos is about ideology. Rather, it is a dispute about interpretation. “elu ve’elu”
