I've nursed both of my kids - due to milk allergies, I had to pump for one to age 2 (daycare wouldn't allow nut-based milks, soy is bad for boys, and rice milk didn't have enough protein - so, breast milk was all that was left). I think it's crucial that women receive adequate accommodations - it's a shame that, in Iowa, I think companies less than 50 people don't really have to follow the rules. In this situation, while I'm super-modest and wouldn't personally be able to do it, whatever works for her is just fine.
I DO agree that there is some breastfeeding militant behavior. Not, by any means, all nursing parents - and I don't think that it's necessarily bad that there are breastfeeding militants. I was literally never exposed to a single other nursing mother than my aunt up until age, like, 25 - almost everyone bottlefed in the late 80s and 90s when I was in school. So, it was really weird to me when I was training an office on software once and a new mother just had to start pumping during the training while I was talking because she was in pain. I didn't have any experience with it, so I didn't get that it was important and natural and not odd.
