^Sure.
You're entitled to your own opinion.
I guess it's really in-my-face the change in the way she talks because I'm from the same country, it's hard t ignore.
As for her representing India, she's kinda is one of the few that people identify as from India (or maybe Apu, from the Simpsons) - my problem being she's not really a good actor.
I don't know how many people think of Freida Pinto when they think of India, but I sure as hell don't think Miley = America or the NJ Guidos = Italy
Out of curiosity, why do you perceive it to be a bad thing that she no longer speaks with an Indian accent? If you're speaking English, you want to speak either American or British English (depending where you live), not English with an accent that makes it difficult for others to understand. It's the same with any language - most people when they learn a language want to speak to the same degree of fluency as those for whom the language is native.
