Wow, okay I don't get any of this.
Lets say we DO ban it, and we force mothers to buy baby formula, which is not cheap. Now we have lots of starving babies/women illegally feeding their child. What would be the solution? Shitty, government-issued baby formula? That would sure go well, wouldn't it?
As for the people going 'OMG SEXUAL PLEASURE' or 'OMG INCEST' guess what the whole human species is based off of? Somewhere, along the line, some kid sucked on his mom's boob. This kid lived on to have his own kids, and his kids sucked their moms boob. Do you see the cycle, yet?
And as for the sexual pleasure, i submit the fact that no sane woman would get off on feeding her child. There is also fact that the only mention of anything going sexually wrong in the breastfeeding article on wikipedia (full of boobs lol) is when the kid is breastfed from 3 to 7 years of age.
I might understand the banning of public breastfeeding, but that's really about it.
