I always believed that tamilians have protected their faith and culture even after mughals and british envasion.. I know a lot of tamilians names as sriram,ramaswamy,bala krishna etc..while in northern india these days fancy names like Raj, Yash are popular..
Lot of music and dances of like bharatnatyam originated from tamil nadu and contents includes lot of stories from ramayna..
What happened to tamilians now..not only they have leader who is atheist and he is denying ram.. Bhartnatyam , Diwali , dussehra would name make sense any more..
