> This usually happens when the person's needs have been repeatedly ignored, either because the person isn't aware of their needs, and thus isn't able to communicate them; or because the person has tried to communicate their needs but not been understood; or because the person has tried to communicate their needs and had their needs disregarded.

This is not true. Low emotional control is one of symptoms and for many autistic this is just a default response. It is literally part of diagnosis. There is no space for needs or rights of others. This is response to someone putting a cut into drawer wrong way or disobeying one of thousands weird rules the autistic person have for themselves and the world.

This frequently happens as a first response to the situation, before any communication could possibly occur.

> Eventually communication fails and all that's left is violence.

Autistic person being violent is violence as any other. And there was no attempt at communication, because man autistic dont understand why the thing needs to be communicated in the first place. They dont understand other dont see the word the same way.

And even more importantly, it is an emotional meltdown having nothing to do with what went on with communication before or not.
