Pa. Ranjith is the director I admire the most in mainstream Tamil Cinema. His ability to infuse this commercial medium with the messaging of an ascendant Dalit consciousness, as he did in Kabali and Kaala, while maintaining box-office success, is astounding. Ranjith is a fearless activist and provocateur. Ranjith hails from a cheri (ghetto) in Karalapakkam, Tamil Nadu and, according to wikipedia, he is from the Paraiyar community.
Pariah has become a slur and a derisive word in English and in Malay and Indians get upset and enraged when they hear this word. Why? Well, this name comes from the cast order that is Indian and Hindu. Attitudes towards it reflect the worst racial prejudice that is innate to Indian culture. The Pariyar are a community that is categorized as outside of the Brahmanical social order. While I deplore the use of the name of this community as a slur in English and Malay, I suggest that it is more important that Indians stop flinching when they hear this word, as that reaction comes from their own racist impulse.
