What does fat “acceptance” even mean? Nobody is hunting them down or anything. They’re perfectly free to be as fat as they want, subject to whatever health issues nature may choose to impose on them
It means they want special treatment and carveouts for their lifestyle choices. Bigger airline seats. More food at restaurants. Special parking spots. Rascal scooters everywhere. Free medical care to treat fat caused diseases. And most importantly, to force society to consider their obese bodies “beautiful” because they know they are physically ugly and unhealthy.
