You must understand that these people are holding American Citizenships. Even if they you to show your loyalty to India, they cannot, at least publicly or they will have a hard time. Imagine yourself - you are in the public glare at all the time - lets talk of Shilpa Shetty that she is an India and now with international publicity, can she proclaim that she would rather be a britisher, etc. It is very easy to say that they must accept that they are Indians - legal protocols and procedures do not allow them to do so. Please understand it.
