At a Christmas party in 2004, a cousin asked me "Do you like Medea?" For a minute I was a confused, since it didn’t seem to be the occasion for sharing our impressions of Greek mythology. But it turned out she was talking about Madea, the massive, loudmouthed, pistol-packing black grandmother who Tyler Perry performs as in drag in a series of "chitlin' circuit" touring shows. Perry sells DVDs of the shows on line, and ten minutes after my cousin put one on I was hooked. I’m not alone. Madea was the biggest new phenom in black America until Obamamania.
