Reform Judaism is a liberal branch of Judaism, though it is often debated whether Reform Judaism is Jewish.
Reform Judaism does not require strict adherence to Sabbath, keeping Kosher, and other basic tenets of Judaism. The yarmulke is not required during services, though both men and women are allowed to wear it even if it is traditionally a male garment. Much like in the Episcopal Church, Reform Judaism has women and homosexual Rabbis, and accepts homosexuality and transgenderism.
Orthodox and Conservative branches of Judaism both do not recognize conversions performed by Reform Rabbis. Even the circumcision of males, or symbolic circumcision in the case of the already circumcised is optional.
