American political commentator Bill O'Reilly regularly expresses his points of view on a wide variety of political, social, and moral issues. He has personally labeled his political philosophy traditionalism. The O'Reilly Factor, since its inception on the Fox News Channel in 1996, has been the primary outlet of his opinions. O'Reilly started his own radio program, The Radio Factor, a few years later. He has also written several non-fiction books detailing some of his beliefs. O'Reilly generally leans to the right on most issues, most notably the Bush administration's War on Terror, but breaks from the conservative and Republican majority on such issues as the global warming controversy, gun control, gay marriage and the death penalty.
