Anirban, don't get upset by some idiots comments. 90% Tamils minus lunatics of DMK are hard-core hindus. You are right, no one in modern India is pure Aryan or Dravidian. Both are subdivisions of central Asian family and hence are minor variants of the same race. Also now with centuries of cultural and mixed breeding we all share same heritage. And by the way skin colour is not related to race. It is just melanin pigmentation to adapt to sunlight.
