Khushwant Singh
Khushwant Singh (born 2 February 1915) is an Indian novelist and journalist. An Indo-Anglian novelist, Singh is best known for his trenchant secularism, his humor, and an abiding love of poetry. His comparisons of social and behavioral characteristics of Westerners and Indians are laced with acid wit. He served as editor of several literary and news magazines, as well as two broadsheet newspapers, through the 1970s and 1980s. He is a recipient of the Padma Vibhushan the second highest civilian award in India.
From 1980 through 1986, Singh was a member of Rajya Sabha, the upper house of the Indian parliament. He was awarded the Padma Bhushan in 1974 for service to his country. In 1984, he returned the award in protest against the siege of the Golden Temple by the Indian Army. In 2007, the Indian government awarded Khushwant Singh the Padma Vibhushan.
As a public figure, Singh has been accused of favoring the ruling Congress party, especially during the reign of Indira Gandhi. He is better viewed as an establishment liberal. Singh's faith in the Indian political system has been shaken by events such as anti-Sikh riots that followed Indira Gandhi's assassination, in which major Congress politicians are alleged to be involved.
Arundhati Roy 
Arundhati Roy (born 24 November 1961) is an Indian author and political activist who was best known for the 1998 Man Booker Prize for Fiction winning novel The God of Small Things (1997) and for her involvement in environmental and human rights causes.
Arundhati Roy expressed her support for the independence of Kashmir from India after massive demonstrations in favor of independence took place—some 500,000 separatists rallied in Srinagar in the Kashmir part of Jammu and Kashmir state of India for independence on 18 August 2008, following the Amarnath land transfer controversy. According to her, the rallies were a sign that Kashmiris desire secession from India, and not union with India. 
Roy has campaigned along with activist Medha Patkar against the Narmada dam project, saying that the dam will displace half a million people, with little or no compensation, and will not provide the projected irrigation, drinking water and other benefits. 
Roy has criticized Government's armed actions against the Naxalite-Maoist insurgents in India, calling it "war on the poorest people in the country". According to her, the Government has "abdicated its responsibility to the people" and launched the offensive against Naxals to aid the corporations with whom it has signed Memorandums of Understanding. While she has received support from various quarters for her views, Roy's description of the Maoists as "Gandhians" raised a controversy. In other statements, she has described Naxalites as "patriot of a kind" who are "fighting to implement the Constitution, (while) the government is vandalizing it". Arundhati Roy severely criticized Hazare and his movement.
