K. Ramakrishna Pillai (1878–1916) was a nationalist writer, journalist, editor, and political activist.
 He edited "Swadeshabhimani" (The Patriot), the newspaper which became a potent weapon against the rule of the British and the erstwhile princely state of Travancore (Kerala, India) and a tool for social transformation.
 His criticism of the Diwan of Travancore, P. Rajagopalachari and the Maharajah led to the eventual confiscation of the newspaper.
 Ramakrishna Pillai was arrested and exiled from Travancore in 1910.

Christopher Hitchens (13 April 1949 – 15 December 2011) was a British-American author, polemicist, debater, and journalist.
 In his youth, he took part in demonstrations against the Vietnam War, joined organisations such as the International Socialists while at university, and began to identify as a socialist.
 After the 11 September attacks, however, Hitchens no longer regarded himself as a socialist, and his political thinking became largely dominated by the issue of defending civilization from terrorists and against the totalitarian regimes that protect them.
 He nonetheless continued to identify as a Marxist, endorsing the materialist conception of history, but believed that Karl Marx had underestimated the revolutionary nature of capitalism.
 He sympathized with libertarian ideals of limited state interference but considered libertarianism not to be a viable system.
 In the 2000 US presidential election, he supported the independent candidate Ralph Nader.
 After 9/11, Hitchens advocated the invasion of Iraq.
 In the 2004 election, he very slightly favored the incumbent Republican President George W. Bush or was neutral, and in 2008 he favored the Democratic candidate Barack Obama.
