"To ban a women's breastfeeding photographs from being uploaded because they show a tiny bit of her areola or nipple is as outrageous as banning a women from showing the same amount of skin breastfeeding in public."
No it isn't. Breastfeeding has obvious benefits for the baby, pictures of breastfeeding do not. The act and the picture are completely different. Facebook are not stopping people from breastfeeding, just as they aren't stopping people have sex. They are merely banning pictures of it. They would ban a picture of fully exposed breasts in any other situation.
