High Functioning

Is What does this actally mean in practice, not the dictionary definition, but for those of us so labelled? Although no ones ever told me I'm high functioning, I guess I am.

Is it a helpful term or unhelpful?

Does it express our experiences properly or reflect away from them?

Is this a term more helpful to NT's than us?

Personally I find the term a bit insulting as well as divisive and dismissive.
