Lankan Buddhist and Indian Hindus are under the delusion that they are of Aryan stock and see Dravidian aka Tamils as their traditional enemy, who need to be wiped out - physically or culturally. It has nothing to do with religion but the identification with a false identity, the 2009 India co-sponsored genocide of 100,000 Tamils in Lanka is a testimony to this deluded mindset
Just like the Jews , Tamils are in danger of extinction in India and Sri Lanka which are their traditional homelands .
Central to the Mahavamsa is the ongoing antagonism between the flourishing Buddhist civilisation established by the Aryan Sinhalese and the menacing south Indian, Dravidian (dark skinned) and Hindu kingdoms in the Tamil speaking areas of south India. Repeated invasions by the Tamil speaking Dravidian kingdoms of south India not only destroyed the pristine Buddhist settlements across the island but also left a residue of Tamils across the north-east.
