Some disabled people are fat.
Some fat disabled people have mobility impairments, and need to use wheelchairs and scooters.
Some fat disabled people need to sit down a lot.
Some fat disabled people need to park in handicapped parking.
Some fat disabled people need to sit in the disabled seating on busses.
Some fat disabled people need to use the bathroom stall that has grab bars.
Some people act like fat people are somehow “not really disabled, just fat” as though the two are somehow mutually exclusive. They’re not. Fat is not a cure for disability. Fat disabled people are as disabled as thin disabled people. Fat people have every right to exist in public and use mobility aids and other adaptations.
Some people act like being mean to disabled fat people will somehow force them to stop being fat and disabled. It won’t. Being mean is not a cure. If you yell at a fat disabled person for needing to park close to the building, it won’t give them the ability to walk further safely. It will just mean that their day got worse because someone decided to be pointlessly cruel to them.
tl;dr Fat disabled people exist, and have a legitimate need for access and accommodations. Being mean to fat disabled people for having access needs doesn’t cure their disability. It just makes the world a crueler place. Don’t be a jerk.
