Essentially. https://en.wikipedia.org/wiki/Protected_group https://en.wikipedia.org/wiki/Protected_group For this case, you'll need to get X to be legally recognized as a distinct race from Y (that has not happened in this case), and minority races have MUCH more protection than ones that are seen as a majority. It also tends to be sensitive to employment statistics broadly and in an area, and "Indian" is often not "under-represented" even if some sub-races are being massively oppressed. It's more of a "yes, race is a protected characteristic. that doesn't mean it matches your definition of race" thing. You could probably successfully sue on it and get it effectively recognized via that precedent, but it'll be a substantial legal battle to get there and many cases do not establish legal precedent.
