It certainly isn’t Indian culture.
Well, then, it's a good thing the new Miss America has been quoted as saying, "I always viewed myself as first and foremost American."
Nothing wrong with her holding on to aspects of her family's history (e.g., with her Bollywood-style dancing).
What you are claiming is that the US has no identity, no culture, nothing and that it is defined by any foreigner coming here and claiming their previous culture is ours.
