When we go to the bathroom, we don't drop trau in front of a public audience and then shame them for telling us to do it in an appropriate setting. There is a time and a place for everything. Exposing your breasts in public is inappropriate. If you must breast feed your baby, us a blanket, a "tent," or whatever you wish to call it, but don't expect this God-given natural process to get public approval because you don't want to cover up. Get over yourself.
