It is first of all factually correct that Muslims of India have DNA wise the same DNA as us. And therefore there is nothing wrong with them acknowledging that their ancestors are Hindus. If they say Hindus are not their ancestors, then who could be their ancestors? Now after all we created Pakistan for those Muslims who didn't consider themselves as ready to live with their Hindu brothers.
