good question, the answer is longish, im sorry.
AS can get hung up on litlle things, small inconsequential things we can get snagged on they really bug us.
Often in the past when people would attempt to insult me, i wouldnt respond at all, as another poster said, nothing to do with self control it was a more aloof distance from the words used, that i was becoming used to in an NT world had little literal meaning, the meaning was inferred, and as i had a literal mindset there was no inference and any attempted insults were dismissed by me.
This relates to ideation and the inability of AS to modulate an appropriate response to a given stimulus.
sometimes a small perceived insult will set off AS people to innapropriate rage/anger.
It is also related to AS objectifying most people and not considering their feelings or words, giving the appearanc eof not caring, because, in my case, i really didt, still dont.
It is related to an increasing self awareness amongst As that non-As have little regard and respect for their choice of words, that we become habituated to them and they have less meaning and impact when used in a deliberately and insulting manner.
