It's just as useless when we say it as average folks, but the fact that people put more weight on Cosby's words because of who he is makes it particularly important to point out that he's preaching from a place that is lightyears removed from the struggle.
I'm not saying people who are breaking the law to feed themselves are doing the best thing, but I'll be dammed if I tell a man he doesn't have the right to do what he sees is in his best interest. Freedom. Liberty. The pursuit of happiness.
I work two jobs and go to school. I'm part of a writing club in my city. I'm involved in music projects with local artists. But I was also recently struggling with addiction, going through my own personal hell, and I brought my parents through it with me. I know how it is to be in that position and not have the capacity to fix your life on your own. With that wisdom, I can't reasonably condone the tone and approach of Bill's speech.
Also, while I disagree with 5th Letter about white cosigns always being a bad sign, I think the fact that Bill was addressing a white audience is important to keep in mind.
