I may agree with deletions / amendments / whatever u call the Aryans did. Your words says that other than Dravidians everybody has did some or other amendments /deletion etc; to their culture. I agree with you but not with the project to carry on.
Forget Rama/sita/Ravana/Mahabharahta/Quran/bible or anyother religious books which i may not know; this project is worse for the environment as we are going to demolish the naturally built sethu and dump the sand in so many places which inturn will be utilised for the constructions and make things more messier.
As per the climatists / environmentalists (world wide) they believe this sethu is restricting so many calamities (Water overflow, tsunami etc;) with which it is doing good for countries.
As for the Indian Govt. savings goes..it is hardly peanuts, they can eat enough money for all the other projects which goes in India but they say they wan't save money.
Pls don't get through the into politics of others and make this beautiful earth & us suffer. Already we are screwing the environment a lot and we can't do more. Let's give a better world to our future generation.
