3,000 Dalits in Tamil Nadu to convert to Islam over ‘govt inaction after caste wall’ collapse

[Doctor Strange]

How did Northern Brahman imposed Dalitism reached deep down South India? For us all black looking Hindus are Dalits. The proportions are higher in the South. What I know is Bengalis converted to Islam en masse when a Hindu dynasty (Sena, who were migrants from north to south earlier) from south India invaded Bengal and imposed casteism on Bengalis. Before that Bengalis were Buddhists. To end the rule of tyranny by the Hindu Senas, Bengalis welcomed people like Bakhtiar Khilji and they conquered with such a small force without any resistance from people.
