The issue is not with the person feeding but with the one who is offended.
Iīm sorry, but the issue is the "snowflaking" all around. Someone wrote that it really is important for the mother not only to be allowed to breast feed, but to be supported. Whatever that means (does the person sitting next to her have to hold her breasts ?)
Breastfeeding normal. Checked
Some offended by it. (for whatever reason, usually "Religion") Checked
Policy: you`re allowed to do so, but - in the interest of in a aluminium tube doing 400 miles an hour in - 68° at 37000ft without police force nearby - we might have to ask you to cover yourself, should an idiot near you make a fuzz, feel offend and canīt be calmed down. Reasonable and fine, checked.
What was the problem again ?
