She's just given up but refuses to admit it. Disabled people can work out and exercise if they try.  My favorite:  "Oh and “make healthy choices” as code for “reduce your calorie intake until you are thin”. My mom pulled this one out when my wife told her to stop sharing fat shaming memes on fb where they were upsetting me. My mom responded “you should help my kid make healthy choices”." Makes me sad someone didn't complain about a tuba playing when they attempted to move.
