Sure, I agree the comments are provocative but it's no cause for offence though, surely? As a white, middle-class Englishman who has never missed out on an oppertunity because of racism, nor indeed been on the receiving end of any racism at all, it is difficult to emphasise with how this appointment has effected the black American population. However, I would imagine that the poorer sections of the black community largely feel that they have been less than equally represented by previous governments, and so look to the appointment of a black president as a change that can only benefit them because someone that is 'one of them' is more likely to address the issues that affect them. Therefore I think it's only natural that they are saying that a black president is preferable to a white one.
I think that the term 'white lies' is a pretty harmless one. I take it to mean lies told by white politicians. Sure, there's no reason to add the 'white' to it, because as Colin Powell and Condi Rice have demonstrated, black politicians can tell lies just as well as their white colleagues. But then again the vast majority of the politicians are white, as are the majority of people in any position of power. Also the standard of living for the average white American family is higher than that of the average black American family. It's understandable that there's going to be some ill-feeling there.
I had a point when I started typing this but I'm buggered if I can remember what it is now.
