Exactly.
I encountered one of these militant breastfeeding mama's once years ago.
She was a very overweight leftover hippie type who was walking through the store shirt WIDE open (which was wide considering her size) and both enormous boobs hanging out for the whole world to see.
It was NOT a pretty sight.
FWIW, I am a huge fan of nursing babies, I did so myself, but never used it as an excuse to make an exhibitionist of myself.
My husband and I had a similar experience in an airport several years ago. It was 250-lb, hippy mama accompanied by wimpy papa and 2 ill-behaved children, who were about 2 1/2 and 4, respectively.
Mama wore no bra and had breasts hanging down well below her waist, which made it very convenient for both of the children since each one periodically grabbed a breast for a sip.
As luck would have it, this charming family was in the seats directly in front of us on the flight, where I was given the most unwelcome opportunity to learn that mama smelled as bad as she looked.
They had brought snacks for the kids, and neither parent made any attempt to clean up any of the cookies pieces the kids dropped on the floor.
