Neurodiversity "converts" are hard to win because people must ultimately recover their own reason and rationality from inside, behind, or under their own anguished pride and prejudice before they see the light for themselves. Conversion is seldom a sudden revelation, for most people must first reflect upon the observations they make while traveling the path they have chosen, and contemplate the repercussion and ramifications of their choices over time, before they will be able to see the inconsistencies in the rubric and rationale of those who misled them.
No Autistics Allowed
There is one issue that both the neurodiversity and curebie crowds can agree upon; they do not care very much for the prominent autism charities that have cropped up over the past few years — though each group has very different reasons for their disapproval.
The majority of well-recognized autism charities dedicated to finding the cause and cure are motivated by the sincere altruism of notable and wealthy people, many of whom have autistic children or grandchildren. They tend to stay on the periphery of the politics of autism, and are generally neutral regarding popular speculation about the cause of autism and the efficacy of experimental treatments. The primary mission of these organizations is, after all, to raise money for research into the "puzzle" of autism, not to make claims of having already solved it.
People who believe that they already know the cause of autism, and how to recover their children from it, object to the way that autism charities refer to autism as a mystery, instead of disseminating literature about mercury, vaccines, and chelation (and lobby to get it covered by health insurance). Some even go so far as to accuse these non-profit organizations of being in on the vast conspiracy to hide this "knowledge."
Meanwhile, autistic people and their neurotypical advocates do not understand why supposed autism "charities" do not appear to be interested in actually helping autistic people, or asking autistic people and neurodiverse families how they feel about autism and what kind of services and support they might need to cope. Autistic people also resent that autism charities do not invite autistic adults to serve on their advisory boards, for they are disabled and they do want and need benefactors who will fund research into how to best educate autistic children so they can reach their full potential, and how to assist and accommodate autistic adults so they can be productive and welcomed members of society.
Instead of reaching out to autistic people, however, these autism charities put up web sites and televise public service announcements that are extremely offensive to autistic people who cannot comprehend how so-called autism "philanthropists" could promote such patently negative images of autism and autistic people.
