Black Judaism
Black Judaism is the collective term used to describe sects of Judaism predominantly practiced by the members of the African communities, both within the African Continent and outside Africa (such as North America). It is theologically characterized by the selective acceptance of the Judaic faith (in some cases such selective acceptance has historical circumstances), and that the belief system of Black Judaism is significantly different from the mainstream sects of Judaism. In addition, although Black Judaic communities adopt Judaic practices such as Jewish holidays and Jewish prayers, they are generally not recognized by the mainstream Jewish societies as legitimately Jewish.
Sectarian discrimination
Sectarianism also exists between Orthodox and Reform Jews, with orthodox Jews often characterizing reform Jews as being non-religious, disobeying the Torah, rarely attending shul and adopting semi-Christian styles of worship. Reform Jews, on the other hand, often view the orthodox as being intolerant of them and of other religions, placing legalistic rules such as the observance of the Sabbath above ethical obligations, being cult-like and hostile to change.
