The "non-Orthodox" versions of Judaism exist with such large consitutuencies becuase most Jewish people, for whatever reasons, some baed on misinformation, some based on accurate information and/or experience, find Orthodoxy distateful. I speak as someone who grew up non-Orthodox, but who is considered now to be "Orthodox" or "Orthoprac." Orthodox rabbis, when they bad-mouth the non-Orthodox segments, or talk of them in patronizing tones ("not Orthodox yet," for example, should look instead at their ownverson--if such self-probling is even possible.
