Given the following passage

"Orthodox Judaism considers views on the part of Jews who depart from traditional Jewish principles of faith heretical. In addition, the more right-wing groups within Orthodox Judaism hold that all Jews who reject the simple meaning of Maimonides's 13 principles of Jewish faith are heretics. As such, most of Orthodox Judaism considers Reform and Reconstructionist Judaism heretical movements, and regards most of Conservative Judaism as heretical. The liberal wing of Modern Orthodoxy is more tolerant of Conservative Judaism, particularly its right wing, as there is some theological and practical overlap between these groups.",
