t is well-known that the Jaffna Vellalars & Brahmins look down as "Keezh Jathi" (Low Caste) on not only the INDIAN TAMILS but also the Jaffna Karaiyers, Dalits & other lower castes. When such is the case why would not the Scythian-Mongoloid Nairs & Menons, who r fairer than even the Nambudiri Brahmins of Kerala, look down upon the Tamils ? For example, MGR (Menon) was white fair in complexion & was fairer than even Brahmins. How could such a person be called a "Dravidian"? Look at OORVASI NAIR , REVATHI NAIR & RADHA NAIR (Tamil actresses). They r yellowish in complexion & look slightly Mongoloid. How can they be Dravidians ? Just bcoz they speak a Dravidian language (Malayalam) they don't become Dravidian.
