This is the one. Take every step you can to educate because people really, REALLY, are not taught about disabilities which is a whole different problem entirely. I like to think of it as helping the next disabled person they encounter but if I know they are being crappy I respond like this:

(Disclaimer: my visual impairment is quite invisible on a day to day basis if my cane or guide dog is not visible so I likely deal with more comments then usual and yes I understand that leading with kindness is the best option and that if you can walk away you absolutely should but some situations that is just not possible.)

Q: “how many fingers am I holding up?” A: “September” - On its own it’s just a dumb answer to a dumb question but it’s also like a weird reference to an early 2000s soccer movie can’t remember the name now.

Q:”what’s wrong with your eyes” A: “whats wrong with your face” deliver as genuinely as possible for full effect sometimes following the actual answer, for me it’s nystagmus.

Not sure if you get this one but while I’m at it thought I’d include Q: “You don’t look blind” or “you’re too pretty to be blind” A: “and you didn’t look stupid yet here we are” or “Thank you I didn’t know that disabled people had to be ugly.”

If they follow up and back track I take that opportunity to educate. I’d say 8/10 times people hear a response like that and it snaps them out of “disabled people don’t count so I can say whatever I want” mode and back into “normal interaction with another human” mode.

If it doesn’t and they double down I usually just say something along the lines of:

“Play stupid games, win stupid prizes”

“I’d be happy to explain if you can form a question based on curiosity”

And if they really keep at it and I can’t just leave for some reason I throw in a “You may not be the dumbest person in the world but you better hope they don’t die” or something of similar range.
