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.
To continue with startrek: Geordie la forge.
He was added because they wanted to represent a blind person, and show how technology can help offset disabilities.
Picard was bald because they didn't care, and Geordie was blind because they couldn't cure him.
The inclusion of a blind person lets them tell the story of how this future society deals with a disability like blindness.
So you can use magic to tell the story of a disabled person. Why are they disabled? Why can't magic help them? How has their society reacted to this?
Maybe it's as simple as simple healing magic can't cure an injury you were born with, so they only have use of their legs through an advanced transformation spell. They live with the worry that a passing dogooder will cast a healing spell that will "restore" their condition and leave them stranded far from the magic that can actually help them. This makes them come across as brusque to people who are "only trying to help".
It's a story, so the magic only does what you want. The point is that we often choose to tell the stories that leave people out because it's more convenient.
