It's incredibly interesting to see people attempt to use their idea of what the middle ages was to back up their own bigotries. If you are wandering about saying "dark ages" you are unequiped to make pronoucements on historical accuracy.
I've said this somewhere else in relation to that post, but it can't be dragged enough, so: in addition to that, it took me about ten seconds to think of three disabled major characters in the most widely known example of grimdark fantasy. One of whom is indeed in a wheelchair part of the time.
literal robots are a fixture in the most popular fantasy settings and yet no one complains but somehow a simple chair with wheels is a problem.
The first question to a "dark ages" user is, "What made them 'dark'?" If they don't know it's a relative lack of documentation, then... welp.
Further - and this is important - fantasy is *not real*. There were no fucking elves on the seventh century so maybe calm yourself down about that. It says a lot about someone when the want to exclude a group from a made up world.
“Dragons I can understand, but disabled people DOING things? That’s just ridiculous.” Do they not hear themselves?
That guy got all of his 'knowledge" about Medieval Europe from Game of Thrones and Monty Python. I have no doubt he's miserable to game with.
Also, in settings with a decent level of magic, surely some of that might be used to support people. (Maybe the rich only I admit but still...)
Northern Europe: the king of the gods chose to blind himself to gain knowledge. Greeks: the armourer of the gods made magic tools to accommodate his disabilities. Idiots: my medieval fantasy would have no disabled people they didn’t exist.
Pfft please I have no patience for childish make-believe ideas about history like "disabled people" riding on "horses"
Not to mention it’s freaking fantasy so there are literally no hard and fast rules about what “should not” be possible. The whole point is to alter reality. Frankly, combat wheelchairs are just as “historically accurate” in a medieval setting as glass windows and a good deal more so than underwear.
