Anyone who adopts Indian culture is an Indian irrespective of religion. Amir and Shahrukh are as Indian as any Hindu/christian and it is Abdul Kalam who designed rockets that ensures Pakistan behaves itself vis-a-vis India. Salman Khan even prays to Hindu gods and celebrates Hindu festivals despite fatwa ( on other accounts he is an idiot but that is besides the point ). If someone accepts India - he or she is an Indian. Even you can become and Indian while still staying in Pakistan. Maybe you already are because you watch Hindi movies , you read Indian websites and evem eat Indian sugar and spices every day.
