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.
Gender separation in Judaism
In Judaism, especially in Orthodox Judaism, there are a number of settings in which men and women are kept separate in order to conform with various elements of halakha and to prevent men and women from mingling. Other forms of Judaism rarely separate genders any more than secular western society.
