The problem with fervent, one-issue lobbyists is that their very passion for the cause can take it backwards, not forwards. They can be blind to the greater good or broad public sentiment.
So it is with the wholly unnecessary dispute this week over a move by the pro-breastfeeding crowd to remove, from a TV advertisement against smoking, a scene showing All Black Piri Weepu bottle-feeding his child. An ad against smoking, not child neglect or malnutrition. And a bottle, not a wooden spoon or a clenched fist.
The scene was deleted at the urging of the La Leche League, Plunket and others. The decision has prompted a profound public backlash against those who would try to force women, and their families, to embrace a fundamentalist view that breastfeeding isn't just the best option, it is the only option.
The censoring of Weepu's bottle-feeding moment brought to the surface the complaints of a substantial minority of mothers and their partners about the actions of hospitals and other publicly funded organisations to force breastfeeding upon vulnerable, incapable or unwilling women.
The passive-aggressive policies of the health ministry and some hospital maternity units to even the suggestion of "formula" or "substitute" milk - and the refusal to assist with bottle filling, heating or feeding - have been resented by many for years.
