There's certainly tremendous zekhut in doing so, but I don't know if that by itself makes one a Chasid 'Ummot Ha`Olam.

Personal note: a good friend of mine, Shmuel, is a member of a Conservative synagogue. He himself is repulsed by abortion and gay sexual relations, and very much a supporter of the traditional pro-life, pro-family, pro-morality ethic, keeps kosher, plus he's very pro Israel--- but I understand the Conservative Jews are officially quite otherwise:

Which rabbis are considered true successors? And which not? And in what manner do they have authority?
(Sincere questions: I'm looking to understand.)
