First of all I don't think there are people who swaying won't work for...eventually. The eventually is the kicker. In the here and now, I STRONGLY strongly strongly believe that there are things in the traditional sways both pink and blue, that are swaying the wrong direction and also things that are neutral but including them is undoing some of the good of the things that actually do sway. And until we get rid of those things, swaying is not going to be as reliable as it could be.
I agree about the 7-8 kids and that is why I spend as much time as I do, researching this issue. I think everyone has a right to have kids of both genders if they choose to and the planet cannot sustain us all having 7-8 kids to do that.
