Who is "we".

If "we" are autistic people, then I am part of "we" then "we" is in error since I don't use term "neurotypical"

Perhaps you should say "I usually use the term "neurotypical"

"Neurotypical"/"Neurodivergent" does the same thing, it just specifies the domain of abnormality. It is still better than "normal", but the difference is of degree rather than kind.

If you are specifically distinguishing autistic and not-autistic, "allistic" is more specific than "neurotypical" (one can be neurodivergent and not autistic) and also avoids any implication than one side is normal and the other is not. (Unfortunately, there is no very good direct replacement for "neurotypical"/"neurodivergent", but one can minimize the impact of that problem by not using them when the real concern is about presence or absence of a particular trait that is within the broad array deemed "neurodivergent".)

I'm autistic and abnormal.
