South indian gods are not hindu. They are known as Muruga, Govinda, Dr. parthasarthy, venkateshawaea. varadharaja perumal, Balaji, Kapaleeshwara perumal. They do not exists for north indian hindus. So dravids were hindus? i don't think so. Dravids were followers of Jina. aryans came much later with hinduism - hinduism is nothing but slavery and casteism of brahmins.
