Udhayanidhi Stalin, Tamil Nadu minister and son of Chief Minister MK Stalin, said on Saturday that Sanatana Dharma is against the idea of social justice and must be "eradicated". Mr Stalin compared Sanatana Dharma with diseases like dengue and malaria, inviting sharp criticism from BJP leaders. "Sanatana is like malaria and dengue and so it must be eradicated and not opposed," he said as quoted by news agency ANI.
