We fight over the topic by making sure we are hiding behind the veils (women?). Why? If we are really so ashamed of being public on this issue, why not do some work which we can be proud of? there are many topics that can be debated in full public view. If I am a Hindu (or muslim or XYZ), I interact with many persons officially and unofficially irrespective religion other person belongs. Anyways, these messages conclude by saying -unity is strength - which every one of us knows. Why are you reinventing the wheel everytime?
