From wikipedia:
Coe is often considered a racist by critics, who use his song ‘Nigger Fucker’ as evidence. Coe claims that he is not racist and that the song is a satire, although in personal appearances he makes an effort to appeal to racist audiences by playing a guitar painted with the Confederate flag. However, for a short time Coe had a black drummer, who was in fact married to a white woman. (He can be seen on Coe’s Live At Billy Bob’s Texas DVD in 2002).
Various other racist songs exist as bootlegs and rehearsals, and have been incorrectly attributed to Coe. The most likely source of the falsely-attributed racist material is Johnny Rebel, a racist songwriter whose music is usually released in single and bootleg form. Coe has been accused of being Rebel himself, though Rebel’s recording career began several years before Coe’s. Coe is aware of this sontroversy, and on his own web page, he has posted the following infomation, written in capital letters, as shown:
"I, (DAC) AM NOT JOHNNY REBEL. NEVER WAS & NEVER WILL BE!
DAVID ALLAN COE."
Also from Wikipedia:
“Nigger Fucker” is a country music song composed and performed by David Allan Coe, first appearing on Coe’s 1982 Underground Album.
Controversy
The song is controversial for its title and racist lyrics, but is regarded by many as satirical. The song’s narrator, whose wife left him for a black man, uses offensive language to describe the intimate sexual love between his ex-wife and her new partner, and refers incidentally to the injustice of being left alone with the children. He says that the knowledge that he has had sex with a woman who has had sex with a “greasy nigger” makes him want to vomit. He criticizes interracial relationships on principle and refers to his wife’s lover using the eponymous derogatory term “nigger”. He ends the song rather abruptly with “So for all you nigger-lovin’ whores / This song is just for you”.
The somewhat simplistic and blunt nature of the lyrics suggest the song should mainly be understood as satire and Coe has, in the past, denied being racist and claimed the song was created solely for satirical purposes. Further, although his work includes many controversial songs, this is the only one with obviously racist lyrics. Despite Coe’s denials of race-hatred, however, many who have heard the song or read the lyrics have difficulty believing him, because there are other aspects of his life that support the charge of racism. For instance, although Coe was born in Ohio – not a Confederate state during the Civil War – he has been photographed playing a guitar emblazoned with a Confederate flag, an emblem of the institutionalized slavery of African American people.
