Who says that the fanatics that comprise the orthodox movement get it more correct than anyone else? Who elected them to make rules for the rest of us? Their points of view are just singular (minority) points of view in the sea of ideas that are out here and have no more validity than anyone elses'. As far as conversion goes, Jews need people. I'd accept anyone who is righteous and of good will into the fold regardless of who performed the conversion. Aside from that, the state should stay out of it and the orthodox can bestow recognition on anyone they want. Halaha has, for the most part, become an antiquated joke, an anachronism. If I need to know what manner of death to impose upon adulterers and homosexuals I'll consult Halaha. If I need to know what kind of spices to burn on my altar to the god-guy I'll consult Halaha. If I need to know how to sacrifice my goats and sheep and how to ritually sprinkle their blood it's Halaha all the way. But if I need to know what rules to abide by in regard to everyday life I'll employ common sense in conjunction with well-evolved, well-settled civil law. Halaha, in order to be relevant is due for a re-write and update just like every other tract of laws and rules, which constantly undergo amendment.
