There is a story,which I had heard from horses mouth. Ravan had a son of extremely white skin colour.Immediately after his birth,Ravana had to send him to far and fest peninsula ,as his astrologers forecast about the child,that the child is very inauspicious for his family and if the child remains in his palace the entire Lanka shall be ruined and his relatives shall be killed.So these Christians of other continents including Asia are off springs of Ravana's Son and are basically Brahmins-the most pious, holy caste of Hindu religion people,who are allowed to worship the God prior to other castes.....lol.....
