Hi Mama22,
I do not know how old your DS is now. But I agree with you that if he is not unhappy being different than I would not be worried as a parent. I know my son says he LIKES being different..it is just who he is. I do keep an eye on it now that he is entering middle school because it is now that peer relationships and fitting in become more critical for most kids.
I actually encourage my DS to continue pursuing and doing the things he enjoys because ultimately those are the things that will bring him enjoyment and friends with like interests.
I would bring up exactly your last point that people are different and not everyone needs to be Mr. Popularity AND it is your DS's comfort and not the teachers' that is most important.
How boring a world if everyone was the same. I think you are right on the money.
