You've literally described the body positivity movement; a social effort to remove the stigmatisation or normalise people with deformities/abnormalities like missing limbs, scarring etc, turned into ACCEPT THE CORPULENT LARD GOLEM AS BEAUTIFUL AND HEALTHY.

The 2nd argument they used was "fat shaming makes me depressed so I eat more and get worse", but to that I say it stops more thin people from wanting to become like you. Nobody was signing up to Onlyfans to sell pictures of their butthole to internet simps when they risked being a social pariah if anyone found out. Some did, but shame kept the vast majority from even considering it as an option. Now girls need to find reasons not to sell themselves since they grow up thinking it's acceptable.
