Background: Ann Hart Coulter was born on December 8, 1961, in New York City, to John Vincent Coulter (1926-2008), an FBI agent of Irish-German heritage, who was a native of Albany, New York; and Nell Husbands Coulter (nee Martin; 1928-2009), a native of Paducah, Kentucky. Her family later moved to New Canaan, Connecticut, where Coulter and her two older brothers, James and John, were raised. She was brought up in a conservative household in Connecticut by Republican parents, with a father who loved Joseph McCarthy. Coulter says that she has identified as a conservative since kindergarten.
Context: Coulter is a Christian and belongs to the Presbyterian denomination. Her father was Catholic and her mother was a Protestant. At one public lecture she said, "I don't care about anything else; Christ died for my sins, and nothing else matters." She summarized her view of Christianity in a 2004 column, saying, "Jesus' distinctive message was: People are sinful and need to be redeemed, and this is your lucky day, because I'm here to redeem you even though you don't deserve it, and I have to get the crap kicked out of me to do it." She then mocked "the message of Jesus... according to liberals", summarizing it as "something along the lines of 'be nice to people'", which, in turn, she said "is, in fact, one of the incidental tenets of Christianity."  Confronting some critics' views that her content and style of writing is unchristian, Coulter stated that "I'm a Christian first and a mean-spirited, bigoted conservative second, and don't you ever forget it." She also said, "Christianity fuels everything I write. Being a Christian means that I am called upon to do battle against lies, injustice, cruelty, hypocrisy--you know, all the virtues in the church of liberalism". In Godless: The Church of Liberalism, Coulter characterized the theory of evolution as bogus science, and contrasted her beliefs to what she called the left's "obsession with Darwinism and the Darwinian view of the world, which replaces sanctification of life with sanctification of sex and death". Coulter subscribes to intelligent design, a theory that rejects evolution.  Coulter was accused of anti-semitism in an October 8, 2007, interview with Donny Deutsch on The Big Idea. During the interview, Coulter stated that the United States is a Christian nation, and said that she wants "Jews to be perfected, as they say" (referring to them being converted to Christianity). Deutsch, a practicing Jew, implied that this was an anti-semitic remark, but Coulter said she didn't consider it to be a hateful comment. In response to Coulter's comments on the show, the Anti-Defamation League, American Jewish Committee and Bradley Burston condemned those comments, and the National Jewish Democratic Council asked media outlets to stop inviting Coulter as a guest commentator. Talk show host Dennis Prager, while disagreeing with her comments, said that they were not "anti-semitic", noting, "There is nothing in what Ann Coulter said to a Jewish interviewer on CNBC that indicates she hates Jews or wishes them ill, or does damage to the Jewish people or the Jewish state. And if none of those criteria is present, how can someone be labeled anti-Semitic?" Conservative activist David Horowitz also defended Coulter against the allegation.  Coulter again sparked outrage in September 2015, when she tweeted in response to multiple Republican candidates' references to Israel during a Presidential debate, "How many f--ing Jews do these people think there are in the United States?" The Anti-Defamation League referred to the tweets as "ugly, spiteful and anti-Semitic". In response to accusations of anti-Semitism, she tweeted "I like the Jews, I like fetuses, I like Reagan. Didn't need to hear applause lines about them all night."
