Autism doesn't exist in several populations, has never existed until 1970s, and places like California have way more autists than places like Texas.
The fact that the autism community disregards this, and instead adopts autism as part of their unchangeable identity, telling Walmart to dim lights because of overstimulation and other accomodations, makes me think Autism is just another Big Pharma/medical community disease, like gender dysphoria, which they profit off in massive amounts and it's for life.
