This whole episode was, as I recall, over 20 years ago, at a time when the Church was still into a pretty heavy reaction against the social upheaval of the 1960s and 1970s. Furthermore, the women who showed up for the conference were probably more conservative and passive about following directions from men than the average Mormon woman at that time. I know that the Church endorses a good deal more flexibility in women's roles now than it did then, and Mormon women have picked up a greater sense of entitlement to self-direction from the trends in the society around them. However, it's also true that since that time, the priesthood has taken complete control of the Relief Society, which was once a completely independent organization, with its own money, uncensored publications, internal choosing of its leaders, etc. If you doubt that, please read up on it.
I'm not at all anti-Mormon, but try to see the faults and drawbacks of the Church and its culture just as objectively as I see the faults of other groups, and just as objectively as I see the positive side of various groups. Overall, I think the Church is an overwhelmingly positive institution, and those areas in which I think it's fair to say it goes too far, are generally areas in which I'd fault mainstream U.S. society and many liberal churches for going way too far in the opposite direction. Nobody's perfect!
