Haredi Judaism
Haredi Judaism is not an institutionally cohesive or homogeneous group, but comprises a diversity of spiritual and cultural orientations, generally divided into a broad range of Hasidic sects, Litvishe-Yeshivish streams from Eastern Europe, and Oriental Sephardic Haredim. These groups often differ significantly from one another in their specific ideologies and lifestyles, as well as the degree of stringency in religious practice, rigidity of religious philosophy, and isolation from the general culture that they maintain.
Religious anti-Zionism
Today, the main Jewish theological opposition to Zionism stems from the Satmar Hasidim, which has more than 150,000 adherents worldwide. Even more strongly opposed to Zionism is the small Haredi Jewish organization known as Neturei Karta., which has less than 5,000 members, almost all of whom live in Israel and Palestine. According to "The Guardian", "[e]ven among Charedi, or ultra-Orthodox circles, the Neturei Karta are regarded as a wild fringe".)
