But you are still equating "people are all fat because they can't control themselves" with "fat people as gluttonous sloths with no self control".

I'm not saying that a desire to look down on and judge other people doesn't bias people's views on obesity. But the main reason people believe that "people are all fat because they can't control themselves" is that there are so many individual stories of people losing weight by following a diet.

Losing weight is easy. I would hazard to say every obese person has lost weight, often times far more than they actually weigh. Maintaining weight loss is a completely different game, and one that is nearly impossible to do unless you address underlying hormonal disorders. The more unhealthy the starting point, the harder that is to do. And the standard reply of "just eat less and move more" is so useless as to be laughable.
