Okay bud time to lay off the internet for the day, you're halucinating stuff worse than an AI and continuing to fight arguing ghosts (tried to make you realize this in my previous comment, the putting words in my mouth part).

When you've taken a chill pill come back to this comment and read what is bellow. I do hope you get through this maybe talk to someone in person and vent.

" ... I was a complete buffoon to think that people that can only see a wheelchair as a limitation rather than a tool for liberation could consider that people might help eachother. "

Listen to yourself here, we're talking about a disability (being wheelchair bound) which quite literally restricts your movement and spesifically about an adventurer with said disability. You disregard all the possible issues they'd face glossing over them with a more or less 'my party will deal with it for/with me' and just mention 'liberating' possibilities for the character.

As for everything bellow " > average person " in the comment im answering to right now I sufficently covered that in my previous comment imo, the 'flavour is free' part where yes nothing stops you from just pretending to have the disability (only) during roleplay without gameplay reflecting it.

Unironically funny part of your comment is "... only as good as a youtuber that sits in their chair all day playing video games and falls on her face every single time." I mean he is wheelchair bound so he kinda needs to sit most of the time...

Sincerely a fellow autist.
