I think its because larger breast sizes and larger hips indicate increased fertility/reproductive potential, its just that the west has special interestized it over the years
yeah i think the whole point of the free the nipple thing is that women cant breastfeed their children in public because it's been special interestized against their will so its like a campaign to make society calm the hell down when they see a titty in general
facebook is generally supportive of progressive movements like these so im not suprised facebook would allow it to be posted
