In fact, there is only one message that the curvy, plus size woman is hearing. You must love your body as it is!
The message that the darker skinned woman is hearing is that she must love her skin. And to prove it, she must flaunt her flaws, take endless pictures of her dimples and rolls and show them to the world.
She must love her body and she must tell the whole wide world about it. We are not teaching our little girls to look at their bodies objectively. We are instead teaching obviously unhealthy overweight women to say that they are thick and sexy and that it is in their genes.
