ThinkProgress features an interview with actor Ryan Gosling and ENOUGH Project co-founder John Prendergast which touches on the subject. From the interview.
Prendergast on Bill O’Reilly, who has attacked the work of other Africa activists like Don Cheadle and Angelina Jolie:He’s [O’Reilly] just pandering for ratings. He doesn’t want to have a discussion, about Northern Uganda or Darfur or any of these issues. They more than anyone — these guys will use these kinds of issues as roadkill for ratings. … What’s really remarkable to me frankly is people like Ryan and Don Cheadle and George Clooney who, it doesn’t help their careers, by the way, to be working on these kinds of issues and to be spending a whole lot of time away from what they do, in order to go crusading around the world about issues that matter to them personally. … So I think there’s no negative, there’s no downside, and people that look for the downsides are sort of the debris, the barnacles, that feed off of this kind of stuff, and that’s how they get their ratings.
