Now that America has voted a brother man into the highest office in the land, we can kiss the ugly vestiges of racism goodbye forever, right? Sure, and if you believe that, Uncle Sam has 40 acres and a mule with your name on it. Sounds absurd, but no less than some of the ecstatic, post-racial punditry heard during the recent presidential campaign. Prepare for some thoughtful debunking when author and Spelman College history professor WILLIAM JELANI COBB addresses "Obama and the Myth of Postracialism" at Georgia State University. Free. 5:30 p.m. 38 Peachtree Center Ave., Classroom South, Room 608. 404-413-2000. www.gsu.edu.
