Coulter has written 12 books, and also publishes a syndicated newspaper column. She is particularly known for her polemical style, and describes herself as someone who likes to "stir up the pot. I don't pretend to be impartial or balanced, as broadcasters do". She idolized Clare Boothe Luce for her satirical style. She also makes numerous public appearances, speaking on television and radio talk shows, as well as on college campuses, receiving both praise and protest. Coulter typically spends 6–12 weeks of the year on speaking engagement tours, and more when she has a book coming out. In 2010, she made an estimated $500,000 on the speaking circuit, giving speeches on topics of modern conservatism, gay marriage, and what she describes as the hypocrisy of modern American liberalism. During one appearance at the University of Arizona, a pie was thrown at her. Coulter has, on occasion, in defense of her ideas, responded with inflammatory remarks toward hecklers and protestors who attend her speeches.
