This whole fight is getting out of hand. Please stop.
I agree with these two. We're getting off topic.Please stop before I have to close the thread. I recognize that topics can be very personal, but there's a point where a debate serves its usefulness, and a point where it degenerates into something that needlessly harms relationships in the community. It's better to let things go instead of crossing that point.
There's a series called Upsidedown Magic, where the main characters and several of the others struggle in a special division of the school because their magic is "Upsidedown" and doesn't work the same as everyone else's. I suppose it's similar to the arcs you often see in these inspiring disability stories, but it doesn't correlate to any specific real world condition.
As for the Ted talk, I think it's easy to forget that the literature kind of takes a necessary path of evolution. Those stories were in many ways essential for bringing attention and respect to the needs of the disabled community, and whatever their faults, I do think they warrant a modicum of respect for the intentions behind them and some of the positive effects they've brought.
~~edit to add,
Upsidedown Magic brings me back to the OP. There are plenty of ways to tell a story about a kid in a magic school that doesn't look like Harry i Potter.... to the point, unfortunately, that there's a whole subgenre of magic school storytelling you also might run afoul of.
