You really think that LDS folk are the only people offended by public displays of breastfeeding? I'm sure you don't, which makes your Peter Priesthood/Molly Mormon line nothing more than an inflammatory comment. If you want to have a civilized public discourse, then be civilized rather than bombastic.

FWIW, my opinion is that women should do what is best for their babies and most comfortable for themselves, while displaying a degree of common sense about social norms in whatever environment they find themselves in.
