I agree with that sentiment 100%, which is why I went to great lengths to encourage readers to make sure they check in with other Autistic people, that my voice is only one voice, that we are not a monolith, that I don't speak for everyone, etc.
Hell there's even a line near the end where I say that there are Autistic people who would disagree with every single line I have written, and that they are worth listening to as well.
So like... what's the problem?
