I have no problem with breastfeeding. In fact, I think it's way better than formula. But I draw the time at exposed breasts. And that's what we are talking about here. There's a page hosted by some wacko Canadian group that shows the pictures taken down by Facebook. Trust me, these are not pictures you want to view at work. While they may not qualify as "pornography", they are certainly highly inappropriate. Childbirth is natural but you wouldn't show pictures of your childbirth to everybody, would you?
And really what does Facebook have to do with breastfeeding awareness? If you are mom, mom-to-be and the first place you hear of breastfeeding is on facebook, you need better pre-natal care.
