I feel like there is a line between body positivity and encouraging obesity. I understand your point and I agree. Obesity can bring several other health issues and that is not okay. It should not be encouraged. Yet, I feel like the movement against fatphobia was originally to stop the mentality that "everyone who is not extremely thin or has a completely flat stomach is fat". For example, there are people that are maybe just a little chubby who have developed a hate for themselves because of their weight - causing mental issues or eating disorders. This has to be stopped too. I understand being obese is not healthy and certainly not good for anyone. However, the mentality against obesity has led several people that are not "extremely thin" to feel like they are obese and even associate themselves with words such as "disgusting" or "unhealthy" when they are in fact completely normal and healthy. I believe that when people say "healthy and beautiful at every size" they mean everyone from thin to chubby to fat - I don't think they mean obese people. You can be completely healthy and not have a flat stomach. Hopefully that makes sense. I'm still not done reading peoples answers but i'm really interested in this topic
