Answer by taking a quote from the following article:

Keith was born in Clinton, Oklahoma, to Carolyn Joan (nee Ross) and Hubert K. Covel, Jr. and is of English ancestry. He has a sister and a brother. The family lived in Fort Smith, Arkansas, for a few years when Keith was in grade school, but moved to Moore, Oklahoma (a suburb of Oklahoma City) when he was still young. Before the family moved to Moore, he visited his grandmother in Fort Smith during the summers.

Keith had a public feud with the Dixie Chicks over the song "Courtesy of the Red, White, & Blue", in 2003 as well as over comments they made about President George W. Bush on stage during a concert in London. The lead singer of the Dixie Chicks, Natalie Maines, publicly stated that Keith's song was "ignorant, and it makes country music sound ignorant". Keith responded by pointing out that Maines did not write her music and he does, and by displaying a backdrop at his concerts showing a doctored photo of Maines with Iraqi dictator Saddam Hussein. On May 21, 2003, Maines wore a T-shirt with the letters "FUTK" on the front at the Academy of Country Music Awards. While a spokesperson for the Dixie Chicks said that the acronym stood for "Friends United in Truth and Kindness," many, including host Vince Gill, took it to be a shot at Keith ("Fuck You Toby Keith"). In an October 2004 appearance on Real Time with Bill Maher, Maines finally confessed that it was indeed a shot at Keith, and that she "thought that nobody would get it".  In August 2003, Keith's representation publicly declared he was done feuding with Maines "because he's realized there are far more important things to concentrate on". Keith was referring specifically to the terminal illness of a former bandmate's daughter, Allison Faith Webb. However, he continues to refuse to say Maines' name, and claims that the doctored photo was intended to express his opinion that Maines' criticism was an attempt to squelch Keith's free speech.  In April 2008, a commercial spot to promote Al Gore's "We Campaign", involving both Keith and the Dixie Chicks, was proposed. However, the idea was eventually abandoned due to scheduling conflicts.

What was his response to Natalie Maines's comment?
