Nobody called you autistic or a social retard. It is a spectrum as well, some people with autism are far more socially retarded than others. If you want though, you can call me autistic. I take no offence at that, not in the last place because I have a ASD diagnosis.

What I said, is that I find autism another [plausible] explanation. Because being honest/direct/blunt is a trait people with ASD suffer from (since they have less of the social awareness which puts the brake on the sharp edges). I find it more plausible than country_of_origin (TBH I find that a -perhaps harmless- form of discrimination/racism), but certainly I did neither imply nor argue that it is the only, sole explanation!
