allies-person:

1. Call your speculation a “theory” even though it does not meet the scientific standards for being considered a true theory.

2. Couch your speculation in lots of detailed information about homo sapiens and Neanderthals that hardly anyone knows well enough to counter.

3. Disguise the fact that many of the “facts” you are relying on are hotly contested by specialists in this area of study.

4. Steadfastly ignore any evidence suggesting the cultural biases of IQ testing or diagnostic rates for any neurological condition.

5. As your main data, use a quiz which hasn’t been subjected to any kind of peer review process and which only you have the data for.  Also, the data is not from a randomized sample, but rather self-referral to the quiz.

6. Make the quiz available only in European languages.

7. In the quiz itself, use a bizarre, antiquated view of ethnicity which requires participants to select only one “race” out of a bajillion different options.

8. Pretend that everyone has equal access to take the quiz.  A person living in Zaire has just as much of a chance of coming across this quiz as a white, middle class American!

9. Use the data from said quiz and numerous unprovable assumptions to fashion a racist theory which pretends to be neurodiversity (while ignoring autistic disabilities).

10. Support “theory” with erroneous assumptions about the histories of non-European peoples.

Voila!  Just follow those ten steps, and you too can erase autistic people of color while being a racist masquerading under the banner of neurodiversity.

This is an excellent summation of everything I found icky about that without being able to articulate it.
