I agree it was innapropriate in a meeting.
But I think it should be a perfectly accepted normal sight at restaurants, parks, and other places children are and people eat and play. It's twisted to think boobs are only sexual, and not twisted to nurse children. Most women are modest anyway when they do it... when was the last time you saw someone 'flop it out' in an obvious way in public? In real life, I mean... not in some weird protest.
I don't have any problem whatsoever with a woman going to the ladies room to breastfeed, or very carefully covering herself with a blanket or shawl while she feeds her baby. Flopping it out for all the world to see is not acceptable in any public venue.
