I have no idea who John DePetro is, but Media Matters seems to be angry with him for suggesting that white people only go to Harlem for prostitutes and drugs:
Summary: On MSNBC Live with Dan Abrams, discussing Bill O'Reilly's recent controversial comments about his visit to Sylvia's restaurant in Harlem, Rhode Island radio host John DePetro stated: "It was a discussion on race and we're talking about Harlem. And by and large -- I lived in New York for years -- white people don't go to Harlem." He continued: "If Dan Abrams and John DePetro, Bill O'Reilly, some white guys are sitting around a table, and Dan Abrams said, 'Yeah, I was up in Harlem last night.' We would think you were either, a) looking for drugs, or, b) looking for a prostitute."
No word yet on whether Media Matters is similarly exercised about John Edwards' comment that young African-American males are headed for jail.
