Had this conversation with someone who chose to no longer be at my table after meeting a blind NPC
Another player who was at the table during the incident sent me this meme after the problem player in question (they had a history) left the group chat.
Felt like sharing it here because I'm sure more people should keep this kind of thing in mind.
The thing I find difficult about disability in a TTRPG is that it's something that is either ignorable due to the character backstory (e.g. they have some mcguffin/ability that allows them to operate without difficulty); or it's going to be a repetitive complication that the party has to constantly work around (e.g. the barbarian carries the wheelchair up every set of stairs they encounter).
If it's just flavour, then it seems like less of a disability than a backstory. If it's a constant hassle, then it changes the nature of the game - it becomes more about a party helping each other through individual adversities. The latter sounds fine, but I'm not sure how I'd run it.
I feel like a lot of the time the best way to handle it would be similar to how the character of Toph is presented in the show Avatar: The Last Airbender. She's blind, but has incredibly good seismic sense through her feet. So most of the time, she can "see" just fine. However, it's still a disability, and there are times where it comes up.
If her feet are injured she can't use them to see. If she's on sand her "vision" will be very blurry and imprecise. If she's flying she becomes completely blind. And she can't read anything written on paper.
The disability is a part of her identity, and it absolutely still matters. But it's not so heavily crippling that it's coming up all the time at the table.
If the disability creates a hassle in some way, then it should give a boon in a different way.
Sure getting a wheelchair up the stairs in a hurry will be difficult, but going downhill will make them double their speed and they can carry a second person.
