passfan: The RCA condemned the practice; they did not expel R. Weiss (of the Rabbi who wrote the article about “sheasani isha”) from the organization. They voiced their halachic disagreement and disapproval with these positions, but they did not conclude that these action were beyond the pale or that they placed those who made these decisions outside the camp.
Indeed, many MO think the RCA should have condemned the Rabba issue more explicitly than it did, but again, very few of them advocated for R. Weiss’s expulsion.
Again I think your missing the point. The point is that MO is more inclusive and has no need to really brand LWMO as conservative. Either the movement will die, or it will move even further left until there is no doubt about what they are, or they will succeed in influencing the rest of the Jewish world and will be legitimized. The final verdict will have to wait until the result is clear, and until then, many in the MO world would prefer cautious inclusion and halachic debate to expulsion, charamim, kol koreis, and more divisiveness.
