Calling me an Indian is also un-acceptable. When ever some one asked me in NA whether I am an Indian, I always say that I am Pakistani. What ever condition of Pakistan is I am born Pakistani. Since centuries my ancistors were born, died and burried in that part of sub-continent which is now Pakistan.
Not towing some ones biased and prejudice line of thinking does not make you an Indian though there is absolutely nothing wrong being an Indian.:)
