In May 2015, O'Reilly blamed the decline of American religion particularly the declining numbers of American Christians on hip hop music citing the genre as "pernicious entertainment" and an adducing factor for contributing to the decline. O'Reilly remarked that people of faith are being marginalized by a secular media and pernicious entertainment and rap industry often glorifies depraved behavior causing the minds of people who consume the music as the least likely to reject religion." American rapper Killer Mike subsequently criticized him for his remarks calling O'Reilly "full of more s**t than an outhouse" and then mocked him while he was a guest "Real Time with Bill Maher".
