I believe that NT tantrums become more sophisticated. Passive-aggression, cruelty, and/or deviousness take the place of simply throwing a nice honest fit.

Neurotypicalism everyday...
Truly enjoyed this.
I wonder if autistic children are less likely to have a tantrum by my definition.
I don't really know whether or not I have had any meltdowns...
Oh wait! I have on tape once when I was a kid and screamed like hell because I didn't want to go into the water (was afraid of sharks), other than that I don't know. Dad has also had some physical struggles with getting me along on a vacation trip or visit to some old friends.
But my parents usually say that I have been extremely calm compared to my NT sisters.
I would have thought that your example with the water was fear..not tantrum & not meltdown.

I like your reasoning.
Perhaps this is why my children didn't have them I don't know why not, but your theory is as good as any.
