Today if you mother is a gentile, you are not a Jew, but tomorrow after the vote you're Jewish. They already had decided that it was not. Rather, they stated that the purpose of this resolution was to send a message that patrilineal descent is not acceptable. I don't feel that you answered my original question. Why is it impossible for the Conservative movement to someday allow patralineal descent when they have in the past voted to do things that it seemed they wouldn't do.
Women counting for minyan and woman rabbis for example.
At one time, the number of Conservative rabbis supporting those issues was a minority. Currently a majority of conservative lay-people believe in patralineal descent. No, because I have never met an Orthodox rabbi who accepts it. Although the number of Conservative rabbis that accept it are the minority, they do exist, and I know this first hand. Today if you mother is a gentile, you are not a Jew, but tomorrow after the vote you're Jewish.
