Socially accepted body shapes and sizes have no place within the body positivity movement - because their bodies are socially accepted. They are catered for in every way. Try being a tall fat woman with huge boobs, i cant even shop freely for clothes
That said though - being obese (not the little podgy overweight lot), actually obese is physically disgusting. It just is. I feel disgusted looking at myself and im not at that level. I do wonder just how happy & confident those really large women feel.. like.. if ya cant even wash yourself properly or reach round to wipe your arse, are you really happy in yourself?
