You know for a fact there are any number of ways you could address my question, but you elect not to and that's fine. Remember, I read your essay. It does not address why it is necessary for females to become rabbis. What aren't males doing that make female rabbis necessary? If it is only about females wanting/choosing to take over these positions, how does that benefit males/male rabbis?
Your lack of any answer at all basically says, Women want to be rabbis, that's reason enough, so let's allow it. No reason to think beyond that it is what women want. In fact, let's not think at all.
