You are an idiot.. 70% of Hinduism is Dravidan worship... Lingam, Rock Temples, worshipping God with flowers/milk are all Dravidan concepts.
Hinduism will live as long as there is God. Dont think there is only life in earth , there is life in other places on the universe and there will be hindus.Atheists can forget about religion and focus on making sense of their lves
