The entire topic is about morals, both individual and social. To claim otherwise shows a certain amount of ignorance.

Morals are not considered acceptable or not because of others within a segment of society; i.e. prostitution is not considered moral because others also prostitute.

You can absolutely consider covering one's self while nursing more moral than not. This does not mean that displaying one's breasts is immoral, but it is definitely less moral than that of covering one's self.

Each person has a different level of morals. It can also be said that different groups of people, making a society, also will accept a different level of morals. I would bet many people in a liberal society, such as New York, would consider baring one's nudity, acceptable, whereas groups of people within the Bible belt would not.

I read someplace that a photo was snapped of her while she nursed and the picture has or will appear in one of the tabloids. The article stated she wasn't real happy about being displayed in such a way.
