In the goddess complex, women are made out to be some kind of goddess because of their birthing ability. The big hoopla over breastfeeding is about turning a biological function common to all placental mammals into some kind of divine power to be worshipped as superior way to "care for a baby." Eh, babies. Who wants to be shackled to a bag of screaming flesh when women have so many other opportunities available to them? According to the goddess complex, only women should be allowed bond with the kids and the father is to be nothing more than a wallet to shut out. In this way the mother maintains control over family dynamics. Honestly, breastfeeding is done for the mother's personal satisfaction as is true for procreation in general. Any woman who doesn't have a brat hanging onto her tit whenever she demands and doesn't stay home isn't a real woman.
As for stay-at-home mothers, why would a grown woman choose to not have job in this day and age for some perceived benefit to their kids? Maladjusted kids are created by titsucking until their ten and constantly being obessesed over by its useless cow of breeder parent.
The final point is pregnancy, birth, and motherhood is nothing special as all mammals can do it and its only the societal glorification attached to it that makes breeding look important. Then theres the bemoanings of childLESS/infertile women, expectation of privileges in domestic life, double standards in relationships, societal drain of resources by breeders...
