In a separate question asking Americans to express their overall view about each of the four religions evaluated, Islam is the most negatively viewed. Nearly one-third of Americans (31%) say their opinion of Islam is “not favorable at all” versus 9% who say their opinion is “very favorable.” This stands in contrast to Americans’ views of Christianity and Judaism, which are far more likely to be “very favorable” than “not favorable at all,” while Buddhism draws almost equally positive and negative opinions at the extremes. Gallup conducted the nationwide U.S. survey between Oct. 31 and Nov. 13, 2009, spanning the Fort Hood shooting in which a U.S.-born Muslim military doctor killed 13 people on the Army base on Nov. 5.
