What does Mina suspect that "new women" will some day advocate?

Mina writes, "Some of the 'New Women' writers will some day start an idea that men and women should be allowed to see each other asleep before proposing or accepting. But I suppose the New Woman won't condescend in future to accept; she will do the proposing herself. And a nice job she will make of it, too! There's some consolation in that."
