The abuse that fat people receive is terrible. Instead of insulting them, we need to teach them how to eat and exercise properly, for the sake of their health!
Do you have a problem with fat people?
They can't exercise because they're fat. If they end up being fit, we need to help them be fat and tell overweight people that it's wrong to be slim
There are many reasons why people would be overweight, and what works on one person doesn't work on another. You would be upset if a person told you how to work your body when you know better.
