Sure. Of course. I am not saying that she ought to have made the detailed case in the actual article. I am mostly just saying that the case is not made, or to be precise that I have not yet seen it.
And, to be fair, she did have the opportunity to do it. There is nothing unusual about backing up one's opinions in an opinion piece. It is done regularly.
Also, the one paper she did cite '('The White Space') did not seem, to me, to add much specific weight to her particular point. But I admit I only skimmed it.
“The White Space”

Let's look at a couple of things here...
First, consider racism in India. Much of the segregation is caste based which while associated to indigenous tribes is actually based on behavior. Persons who are designated Scheduled Castes or Tribe used to be called Dalit, but their cultural behaviors involve something seen as unclean in Hinduism...such as killing animals (fishermen, cattle ranchers, ...) or eating the animals (non vegetarians). Touching them is thought to be impure and if it happens one needs to ritually cleanse the self.
So, ..., the Indian Americans were standing next to several White persons, appearing integrated into that crowd. They likely perceived it as such. Were the White persons actively disenfranchising the Indian Americans? No. Perhaps one was taking the video, but the perception appears to have been of acceptance.
Moreover, if the Indian Americans were grossed out by non-vegetarian-ness of the blacks, then why not also all the White people around them? Why were they trying to integrate with presumably non-vegetarian Whites, sitting next to them, not finding it impure, not scolding them? Along with that, why use American vernacular racist terms that have more to do with European historical racism than Indian terms such as Dalit?
Well, I still haven't read the article, and no, I don't have an informed opinion, except to say it doesn't appear to be implausible to me that these two characters were trying to act American, which maybe they are by birth....but are they by behavior?
