Lilith while I can agree with you that the message conveyed wasn't the one we'd want our children to receive. I don't really see it as a threat because the most important messages about love conveyed are the examples acted out right in front of them. If we love with expectations then I'm afraid that's their definition by perception and the odds are they'll be more likely to as well.
As for the Barbie image, give me something a little closer to a Delta Burke in a Pixie's style thank you.
