bpt,
But consider this: were a male to act in the manner you describe, fully covered by a partition / blanket / ect, he would be removed from the plane in handcuffs. And rightfully so.
This is a flawed argument, as men do not nurse infants.
Given the case described here of a woman on an airplane with a nursing infant who does not accept a bottle and where using the lavatory is unfeasible, should the woman deny her hungry child food and let him cry?
