I always thought Schizoid was just slang for Schizophrenia but no according to Wikipedia it's basically just autism.
So yeah autism, all the popular hallmarks of insulting or calling someone an autist fits the Schizoid description to a T. Which also fits calling people permavirgins and all the implications behind it. It's a political mental disorder.
>but the actual Autism disorder has nothing to do with Shizoid.
Since the great big book that Psychology hinges on for all their pseudoscience has expanded Autism beyond the point of simply being a development disorder, twice already, yes it pretty much is the same thing now.
