We are saying the same thing. I'm saying that someone is a foreigner _not because of the color of the skin_, but because they are identified, in a way or another, as a foreigner, and put in one or more of the outgroup.
The whole Black IQ question is focusing on the skin color not because the skin color in itself is relevant, but because the Black IQ question wants to focus on foreigner and that the skin color is an easy way to do that without admitting it. And it is 100% consistent with what you say: in the Black IQ question, what the people who give credit to this theory refer to when they say "black" is NOT including southern Indians with equally dark skin. It is the proof that it is not about skin color, but about racist prejudice against African-Americans.
Then, yes, of course, there are several outgroups, and racism applies differently depending on the circumstances. There is obviously an entanglement between past history and recent history, but I don't understand what you are trying to come to? That the Black IQ question is because some people hate some people while these people are being totally neutral on the skin color? So why is the Black IQ question regrouping people based on the skin color as a proxy for a specific outgroup?
For the element where I say that some black-skin people integrated for generation are still way too often classified as foreigner, this is not contradictory to anything you are saying, and I doubt you can just say it's incorrect based only on few examples, as I have few examples where it is the case (the same way you cannot say "it is not correct that some cats are white because I can give you examples of non-white cats": as soon as I've observed white cats, my sentence is validated, and the fact you haven't seen any does not change that. If it exists some black-skin individual integrated for generation that are seen as foreigners, then it means that what I'm saying is correct)
TL;DR:
People are not racist against some other people fundamentally because they have a different skin color (this would be a very ridiculous assertion). They are racist towards them because they are identified as an outgroup. Then, the skin color is used as one of the proxy to classify other people in this outgroup (and other characteristics can invalidate this classification even if the skin is dark, this is why black-skinned Indians or very tanned white people are not often classified as black).
