DL Hughley and Don Imus: Double Standard or Freedom of Speech?

Comedian DL Hughley has received some flak about comments made on The Tonight Show with Jay Leno. Those comments revived the Don Imus 'nappy-headed hos' controversy but to a much lesser extent than the outrage Imus generated.

Thus far, the only major show of dissatisfaction with Hughley's comments was in Texas where protests led to the cancellation of Hughley's performance. Check out the clip below. Did Hughley get a pass or are some Blacks off point on this one?
