Thinking about bias...

Watching the Sotomayor hearings play out, I am puzzled by the insistent questioning about her "biases" that she would presumably bring to bear unfairly on her rulings. Does this mean that white men appointed to the court bring no bias whatsoever and therefore are the only reliable arbiters of this society's legal tangles? Were the people pursuing this line of questioning really serious?

Just sayin,' that's strictly a rhetorical question. I watch in wonder...
