Nope read the post again, and try not to get all butt hurt about it. Nobody is afraid of a nipple.
It's about natural the bodily function of breast feeding. Urination, flatulation, and defecation are also natural bodily functions. So why is it they are not (socially) acceptable in public and breast feeding should be?
Your health and sanitation excuse is not valid. Waste is all around us, we are bombarded by bird urine and feces 24 hours a day. Ground animals urinate and defecate all around us 24 hours a day. We have vast sewer systems that carry waste water under our feet in pipes to be recycled at a waste water treatment facility and then returned to the environment to be reused and consumed over and over.
We are talking about the socially acceptable aspect of natural bodily functions. Why should breast feeding be allowed, but not urinating, flatulence, or defecating in public?
Personally, I don't care. If a mother wants to breast feed in public, I am fine with it.
At the end of the day, lots that is natural need not be on common display, and I think we all need to use just a little judgment, when we are able to.
Has nobody ever been in that desperate situation when you're on a public thoroughare, possibly having had several beers too many, and simply cannot hold back that next pee? And all the businesses are now closed, and you've got 10 friends (and a bunch of strangers) around? Guess what -- you pee. Yes, you try to be discrete, in a shaded corner, with your back to everyone (or asking a friend or two to stand in front of you if you're female).
Same thing with everything we do -- there are social norms (and they're not the same everywhere, by the way!), and we try to live within them. A woman breastfeeding can use a simple piece of cloth 2 or 3 feet on a side to make it easier for everyone to feel more comfortable (though even then, some won't, and will think the whole thing abominably shameful, but then they have a problem).
These are not hard things for sensible, mature people to cope with -- unless they've been indoctrinated with so much of that old religious bushwah that they can't handle the notion of a woman enjoying an orgasm, or a man taking a little solitary pleasure when nobody else is around.
