WASHINGTON (CNN) – Rep. Hank Johnson is standing by his comments that Rep. Joe Wilson's "You lie!" outburst at President Obama "instigated more racist sentiment" and could lead to a resurgence of the Ku Klux Klan.
Johnson, a Georgia Democrat, wrote in the Atlanta Journal Constitution on Monday that he doesn't think that most of Obama's opponents are motivated by racism, but that he believes Wilson's comments "winked at a racist element" and that there is a small but "racially motivated fringe" among those who disapprove of the president and his policies.
"Wilson is a canny politician," Johnson said. "His outburst was a carefully calculated appeal to a particular constituency who question the legitimacy of Barack Obama's presidency. The symbolism of his act, which violated the rules of the House and attacked the dignity of the president's office, emboldened and validated those who believe that President Obama, despite having been lawfully elected, is an illegitimate occupant of the White House."
Johnson said that some feel "resentment that the president of the United States is a black man" and that the "risk of violence is real." He said he believes some of the angry protests during town hall meetings over the summer were also motivated by racism and warned that if that element of some opposition is ignored, it will "fester, grow and come back to haunt us in ways we haven't seen in decades."
"That is, ultimately, what my comments were meant to convey," he said. "The United States has shown a capacity for progress and self-improvement virtually unprecedented in human history. But let us not believe that the bad old days are so far behind us that racially driven violence could not once again rend our social fabric."
Johnson ultimately said he will not apologize for saying last week that Wilson's comments could lead to a revitalization of the Ku Klux Klan.
"I guess we'll probably have folks putting on white hoods and white uniforms again and riding through the countryside, intimidating people," Johnson said on September 15. "That's the logical conclusion if this kind of attitude is not rebuked."
