Firstly, since the term 'social skills' itself was defined by & for NT societies & encompasses different behaviours depending very much upon everything from historical period to nationality, customs, social norms, faith community, class & environment, I find it difficult to extract a universally acceptable scientifically sound & definition of what social skills are. The line between Aspies who are sociable, communicative, friendly & extroverted and NTs who are introspective, introverted & on the quiet side is vague.
IF being able to function in a social setting as necessary to secure one's existence is a measure of social skills, many of us here are wives, fathers, husbands, parents, friends & workers of many different kinds. We are able to go buy food (either in person or online or both) we socialize regularly here online & have jollied each other along over the years. Some of us are able to work with the public in retail settings ( I could never do that).
We HAVE excellent Asperian social skills. Most of us seem to have a different level of interest in unrelenting face to face socializing. We seem to value and require more alone time on average than most NTs. Also, some of us are simply not motivated to have a bunch of friends (me). This doesn't make us unskilled; it makes us different. There are also a great many Aspies who express deep loneliness & long for friendships or a relationship but cannot find suitable people. For what it is worth, many NTs feel the same way & many are hanging out with people they do not truly feel a connection to or even like very much. They are faking it in order to not be alone or look like an outcast. Many of us are not willing to do this for very long because our logical nature tells us that it is fake, insincere unsatisfying & exhausting.
I have witnessed the sorry spectacle of NTs who are sociable to the point of obnoxiousness: do they have greater social skills than the quiet Aspie in a hoodie & reading a book? So long as their sociologists & shrinks get to define the terms & their parameters, most conveniently, with the assumption that their understanding & behaviours are the 'normal & correct' ones, smacks of pseudoscience such as scientific racism & other absurdities.
