NEW HAVEN -- Standing at the front of an auditorium that looked like a castle dining hall, cartoonist Aaron McGruder, of "The Boondocks," leaned into the microphone and said, "All right. Yale." And the packed house applauded, just like that. Through the rest of his nearly two-hour talk on Saturday, McGruder, a 28-year old who looks no older than his college audience, drew guffaws, groans, and loud applause at Yale University's eighth annual Black Solidarity Conference.
