I've only heard from one person I know irl who ever had anyone comment negatively on breastfeeding in public (it was an old man who didn't like my friend feeding her daughter in a restaurant🙄 ), and I know lots of women who have done it, so I would agree that the controversy isn't actually widespread. Most people seem to think that it's good for the baby and something a mom should do (which opens a whole other area of judging mothers, because of course it does).
