Joseph is too young to remember past GOP appeals to racial bias, such as Richard Nixon's "Southern strategy," Ronald Reagan's "welfare queens" rhetoric and George H.W. Bush's infamous Willie Horton ad. He believes Obama should have done more to promote economic growth.
Yet Joseph is often called a racist when he discusses politics. This inspired him to film a satirical video, "Bob is a Racist" (http://bit.ly/SrvPAW ), which lays bare the frustration of many conservatives.
"Things have changed a lot since the 1980s," Joseph, a video journalist for a conservative media group, said in an interview. "I don't think food stamps equals blacks. We don't want people to be on food stamps, black or white."
So how many conservatives are truly biased against black people? "I don't know," Joseph said. "But it's hard to figure out when one side is assuming that it's everywhere."
It's not everywhere, acknowledges Courtland Milloy, a black columnist for The Washington Post. In a recent dispatch, Milloy described a widespread belief among some black Washingtonians that Republicans are using race against Obama.
"But there unquestionably is racism in some of the opposition," Milloy said in an interview. "And it should not just be up to black people to identify it and have to deal with it. This is an American problem. It's not just a black problem."
That can be difficult for folks who don't see a problem. Joseph, for one, doesn't buy the foundational idea of unconscious bias, that America remains afflicted by a racist past. "You get in the real world, and I just don't see it," he said.
For him, the bottom line is simple: "I know I'm not a racist, and the conservatives I know aren't racist."
The perils of potential offense can be everywhere. Glisson, director of the racial reconciliation institute, recalls a recent meeting with an unfamiliar group of people, including some African-Americans, and telling them about a good location for a professional retreat.
Then Glisson, who is white, mentioned that the location had excellent fried chicken.
She immediately sensed a change in the atmosphere: "They didn't know that I love fried chicken." It's a common occurrence: a statement that can be interpreted either way.
Evan Woodson, a black student at Oklahoma State University, often hears other black people call something racist that he sees as benign: "People seriously act as if whitey is still out to get them in 2012 in Stillwater, Okla. I don't think that's the case anymore."
Woodson does believe that the legacies of slavery and Jim Crow still create disadvantages for African-Americans. But when it comes to politics, he sees racial transgressions from both parties, such as Vice President Joe Biden telling black people that Republicans "want to put y'all back in chains."
"No matter how you cut it, politicians constantly seem to be accusing the other party of racism," Woodson said, and that prevents people from having honest conversations about actual racism. "People can't identify real racism anymore. They're lost in all the race-baiting."
Even when racism was a raw fact of American life, it wasn't always easy to identify. "Something is holding me back / I wonder, is it because I'm black?" Syl Johnson sang in the haunting 1970 soul classic, "Is It Because I'm Black?" (http://bit.ly/QpEmx7 .)
In an interview, Johnson, now 76, said his song was inspired by a twisted saga of land stolen from his family in 1930s Mississippi. He said the song remains relevant today because, he believes, Obama's blackness is indeed holding him back.
And yet: "Everyone that's white ain't no bigot," Johnson said. "Otherwise Obama never woulda become president."
