Yeah, I can just see this conversation:
Me: "Meine Schaetzchen, I forbid you from joining or forming any sort of independent sorority that is only for women."
Her: "Why did you volunteer to sleep with the chickens from now on?"
If my wife wants to join or become a founder of a free-standing, independent sororal organization, there is no way I could object. Likewise, if they have an initiatory structure, don't allow men to join, and have esoteric practices, what of it?
It is not the place of Freemasonry to dictate what women do entirely among themselves, any more than it would be the place of a sororal organization to dictate what men do among ourselves. So long as it does not impinge upon life outside the fraternity or sorority, what is the point of debating the issue?
One might as well ask, as Americans, if the Swedes are to be permitted to hold their political elections every three years, in the month of March. It's simply not our business to decide that issue.
