I write about disability (or rather, include disabled people) in my fiction (some fanfiction, some original) because I think it's important and I think it likely always will be a part of life.

I'd love to see those fics. What fandoms do you write for?

If my mother wrote fiction, I couldn't condemn her for making a world in which she wouldn't have to go through this.

That's a damn good point and something I really did not think about, and for that, I fail. Hard. I was addressing able-identifying writers erasing disability, and didn't stop to think about how the situation would change if the writer were a PWD. So thank you for reminding me of this.

Still, I wonder how much of the lack of representation of disability is not because writers are dismissing people who are "not normal" -- though that's the effect -- but because people write out what scares them

That's something definitely worth thinking about. I couldn't begin to say, but it is something to consider. Very valid point.
