But... the person you're replying to didn't say you don't need to use a wheelchair. They said that if someone genuinely doesn't need to use a wheelchair, using one will likely have negative effects. Which is just, like, true? In my head, it's roughly akin to saying, "If you consistently take a medication you don't need, you're probably going to wind up needing a different medication to counteract the negative effects of the medication you unwisely took."
You're completely right that wheelchairs are liberation tools and shouldn't be vilified. And as someone who needs medical intervention to survive, I understand your frustration with ableist rhetoric. I just think your reading of this one is a bit off the mark.
Thank god. I hate being on websites with kids.
