THIS is why I really, really want you guys not to get too hung up on theories about how gender swaying works. WE DON"T KNOW and at any point in time it may be proven that there is some other mechanism that no one has ever dreamed of coming in to play.

Don't go over and over every theory looking for the magic bullet because it may end up being some other thing all together that we haven't even thought of yet.
