I don't think you mean empathy. I think you mean emotional intelligence.
And it IS an important skill in our current cultural climate, and without it some things can be a struggle.
ASD is very hard to deal with as a parent because you assume the cause and motivation behind behaviour is the same as it would be for an NT child and it very rarely is. That makes handling and 'getting' your child very difficult, and unfortunately even more so for teachers, carers and the outside world that don't have your motivation to do so.
The more you learn about ASD, and the more you learn about your child in this context, the more you will 'get' that many (depending on personality of course) are actually very sensitive and working hard to figure out the social side of things.
Amber once wrote a guide for her church that she shared on here and it has probably been one of the most enlightening things I have read wrt to understanding my ds. Basically, it was to imagine that you had to attend a church of a religion that you had no understanding of. When you enter, the room is set out in an unfamiliar way. You are unsure of where to sit so look around for clues anxiously and then choose somewhere, which, turns out, is reserved for someone else for some strange reason that you cannot figure out but everyone else seems to know, which gets you a few tuts and a few strange looks. The congretation all stand and sit at various times without any perceivable triggers. You 'thought' that you'd figured that you stand for songs, but obviously got it wrong because the last song, where you stood up, everyone else remained seated etc etc etc. And that is your life, and you are trying very very hard. As and when you get things wrong, people can sometimes be very hostile, or at the very least, just prefer you to not be there.
This is going to be your son's life, and he needs your help to reduce the hostile incidences and reduce the number of people that would prefer him to not exist. It isn't his fault he was born with this struggle.
