I wasn't offended by your original statement, but I can see how someone could take offense.
The point is that if race wasn't an issue, then why bring it up? Would your story be any less effective if you just said "people" and not "asian people"?
There are folks out there that are prejudiced against others for whatever reason. Perhaps folks that don't like Asians will read your story and have another reason to hate. It's perpetuating a notion that other may use to justify their own racist behavior.
