Dinakaran was truly 'secular'. His death was condoled first by another truly 'secular' politician - Karunanidhi.
Dinakaran is an evangelist and his work is to convert 'communal hindus' to 'secular christ'. This secular social service is loved by one and all 'secular' politicians.
Dinakaran helped 'secular' parties by producing mass vote banks. Definitely the reason why 'secular' karuna gave the first condolences.
