What is the controversy with neurodiversity?

A particularly common objection to neurodiversity approaches is that they cannot be applied to autistic people with intellectual disabilities, who are sometimes referred to as “poorly functional” (a term that many neurodiversity advocates reject because it stigmatizes people with intellectual disabilities and disdains the challenges they represent). The neurodiversity paradigm has aroused controversy among disability advocates, and those who oppose it argue that it risks downplaying the suffering associated with some disabilities and that it requires acceptance of the things that some would like to see addressed.
