Dussahra , Diwali and South India

I was wondering lately the reason for Mallus not celebrating Dusshra /Diwali. And this lead us into a discussions about Ram and Ravan. A google search added some more info. I found many references which said that the fight between Ram and Ravan was more of a fight between the Aryans and Dravidians. The assuras one has heard about are in fact the Dravidians ,the early inhabitants of the Indian Subcontinent and the Devas are Aryans who had later on invaded India. The fact that Ravan was one of Asura Kings supports this fact.This also leads one to suspect that probably all the Hindu epics were written by Aryans and thus that would explain why Asuras are depicted as the evil ones. Now that was a great revelation!! In any case personally I feel that Sita might have been better off with Ravana because Ravana was strong enough to be ready to declare her as his wife without really fearing about the opinion of the mob . Apart from that he didnt have any constraints accepting her as his wife even though she had spent considerable time with Ram. Ram obviously appears weak in front of Ravan.
