The sturm and drang around breast v. formula feeding is much like the trouble between public spaces and the women who dare to breastfeed in them. It is at once an invention of the reader-starved media as well as a real conversation between people trying to sort it all out. Jezebel's statement gets right to the heart (the bosom) of the matter: "Boobs are for bodyshots not for baby-feeding" in which they decry Facebook's decision (covered earlier by Pierre) to take down all pictures of boobies (breastfeeding ladies). Because boobies? Always pornographic...
On the other hand, if straight men (or Facebook, whatever) find breasts so overpoweringly, dizzyingly fascinating that even a breastfeeding mama inspires red-faced awe and trembling, then perhaps we should just sit back and enjoy the power? MetroDad wrote a great guy's guide to breastfeeding etiquette in which he admonishes men to try not to ogle, but also understands about the occasional need to sneak a peak.
Breastfeeding requires breasts. If society is so completely unable to contemplate that human body parts can be both functional and sexual (need I point out the obvious? see Queer As Folk if you're still confused), then we're in bigger trouble than we can even imagine.
