This is not accurate.

This is not accurate. One common theory of the mechanism of Autism is over-empathizing with people (as well as animals and objects) to an overwhelming degree. I am sorry you’ve been in two awful relationships with Autistic people, but those two folks do not represent the whole of variation in that group, and it was not their Autism that made them abusive. Autistic people are at a high risk of being abuse victims, in fact, because they are often trusting or have trouble identifying red flags.
