None of us are in a position to make assumptions about another person's possible diagnosis, even if we think that by using the 'correct' terminology it somehow limits the damage. With growing awareness around Autism, there has also come this idea that we are all 'on the spectrum' - we're not. ASC is a real thing which makes life difficult for lots of people. It's not something to throw around as a way of explaining someone (who you don't know's) behaviour.
