"There is much wrong with a posse of women using their babies to make a political point. That is abusive, has nothing to do with the baby and everything to do with the sillier side of feminist politics."

Abusive???? Tell me how or why in heaven or earth that this action would harm the babies or anyone else. Some twit harassed a mother who was trying to feed her child in a manner to which she was entirely legally entitled. She didn't gather other women to march around with pickets signs and try to turn other people away from the business; a group of women got together and, by doing something that wasn't even offensive to any normal person, probably embarrassed the poor widdle jerk just a little in the process of teaching him something. Say for one moment that the group action could be considered "silly": there are a helluva lot worse ways that people could respond to something totally inappropriate than by doing something totally harmless and slightly "silly" to call attention to it.
