In particular, the author has a very abled perspective, and it is very clear from reading it, as someone who most definitely is mentally ill, albeit what a psychiatrist would call functional, that they see their abledness as something good (not necessarily in contrast to not being abled, but in itself)

Which is complicated to me... it's perspective is protective of not having a mental illness, we are needing to "save" people from the pitfalls of being labeled as having a mental illness. And that isn't to say that I think everyone fits into having a mental illness, far from it, but just that maybe that perspective is problematic in some ways

There are certainly problems with being misdiagnosed, whether you are not mentally ill or simply have a different illness, and, like I said, I still want to engage with the books premise whether or not I agree with it. Just, I have mild problems with the perspective, it feels off to me..
