Satmar, Neturei Karta and other extremist elements in the Montreal haredi community have threatened large protests against visiting Israel gedolim, Rabbi Aryeh Leib Shteinman and the Gerrer Rebbe. Why? Because Rabbi Shteinman supported the Tal law and the formation of a haredi IDF unit. The two have cancelled their planned visit to Montreal, despite pleas from more moderate haredi factions, who argued that staying away would strengthen the extremists. Protests are said to be planned in Monsey, New York, as well.
