Oh yes, I agree with everything you said except on being able to test for being neurotypical. That's like expecting a test for being "not sick"/"not unhealthy"/

Oh yes, I agree with everything you said except on being able to test for being neurotypical. That's like expecting a test for being "not sick"/"not unhealthy"/"not physically abnormal". You can test for specific conditions or indicators and get negative results, but there's no test that can produce a positive result of "nothing wrong".
