Sorry, but is is the Political Left in Israel that empowers the radical haredim. Many Leftists like these extremists because they are anti-Zionists and oppose the religious settlers in Judea/Samaria. It is the Labor Party and MERETZ who gave control of the Chief Rabbinate to the Haredim, feeling it was better that the "official face" of Orthodox Judaism be extreme, again to oppose the settlers and to make Orthodox Judaism seem very extreme to the non-religious population. This is completely cynical.
