Sarcasm and the Literal Thinker stereotype

An autism stereotype I heard during a recent talk was "sarcasm hit-or-miss," as further evidence of a child being autistic.

But isn't "sarcasm hit-miss" is equally true of the NT population, as not everyone gets sarcasm.  

Sarcasm is not an autistic identifier and this idea seems to derive from another misconception;  

that ALL autistics must be only literal thinkers.
