They keep trying to make this a moralistic thing, like society is punishing them for doing something. The thing is it's mostly cause and effect. If you're fat you not going to be as attractive, health, or able as someone who's not. It's just basic Physics, Biology and Anthropology.  It's like if I designed a car but was really lazy and only did the bare minimum to make a car that ran. But constantly said, "this car should be as fast, efficient, and good looking as a Tesla, society is oppressing this car by not letting it be like a Tesla." It's not a punishment handed down from socioty for me being lazy in the design, is't just the consequences of not working harder and making a better car.
