I really really hate that term..what the heck is it meant to mean, anyway? (I know what people imply when they mean it....someone who will not accept anything other than breastfeeding)...But adding Nazi to the term is really quite defamatory. The Nazis thought it was fine to torture and murder a whole race, the practice of genocide. It isn't to be taken lightly.
I am sure I am going to get a whole load of posts of people telling me to lighten up, but this term really does upset me.
I think passionate breastfeeder (as we all should be) is more acceptable.
