I would bet on it being a little bit (well, a lot) of ablism mixed with people wanting only answers that they personally can use. Which circles back on the ableism… people don’t want to believe that they could suddenly join this minority group at any time.
I had to be in a wheelchair for a year. The internalized shame from pervasive background ableism is horrible.
It wouldn’t have been so bad if they didn’t burn everything at the end. I mean, I get that sanitation in that situation was pretty darn important, but it was the author’s choice to choose something that required that outcome. That ending made me sad for a long time. Definitely didn’t know how to handle it. Not sure I can even now.
