No it isn't. I don't believe that NT's treat Autistics this way.
More than likely it is just part of the human condition called ego. Bullies and narcissists all have huge egos and prey on easy to victimise people, it just so happens that Autistics are especially vulnerable to these types of unconscious treatments and manipulations (Myself included).
People just do what they do, any human can be mean and cruel, and not just to Autistics. I believe people simply act according to their level of consciousness.

I don't have Autism, I was born this way. I'm simply called an Autistic.
