I think you've stumbled upon the problem. Most, if not all of the people here that are against breastfeeding in public have equated nursing with sexual behavior or elimination. They can't seem to see the difference, that's why they're offended. Other than that, they're just nosy and judgmental.
No, they're just pointing out holes in the logic. I certainly don't have a problem with breastfeeding in public, but the arguments put forth in this thread have been lame. Saying that something is "natural" is an incredibly weak argument and should be dropped as it does more harm to your position than helps it.
"Sexual" is in the eye of the beholder and the women in this thread want to be able to dictate what is considered sexual and what is not.
Like I said before, if that woman's boss told her that she could breastfeed in his office and he'd like to watch since it's such a beautiful, natural process, he'd immediately be slapped with a sexual harassment suit.
Public places = public spaces.
I'll be nosy and vocal about anythning I want.
You have the choice of packing up your breasts and going home if you don't like it.
