trans people, might reasonably be described as people "whose attempts to make friends are odd and typically unsuccessful". Since that phrase got ripped straight off the dsm diagnostic criteria for autism on https://www.autismspeaks.org/autism-diagnosis-criteria-dsm-5 , it should not be any surprise whatsoever that these are correlated (same as with any other category of significantly 'odd' people).
This is a thoroughly bizarre assertion. Why can trans people be described thus?
