It's interesting that people see it that way. Around here, when someone does something incredibly stupid, one of the things you can say to them is, "Were you not breast fed as a child?" and it's seen as inferior, developmentally and socially. I didn't run into the same kind of slang other places that I lived, so while I'm not entirely certain, that sort of thing speaks to me of a different culture where I grew up... which in turn leads me to wonder if it's a regional thing to feel that you have to "Put that thing away". It's so ingrained where I grew up that it's always sort of been "If I ever have a baby, of course they'll be breast-fed. There isn't any other way." ... and with that comes, I think, more acceptance of doing so in public. I see women doing it in restaurants, and on benches in the mall (granted, out-of-the-way benches, but still benches in the mall's atrium). It wasn't until I moved somewhere else that I began to realise that this was not the way things were everywhere.
