There is a hell of a lot of confused talk about racism right now all over the political spectrum.
The right wants to deny that any opposition to Obama is racism, but some of it obviously is. They find some politically acceptable reason for cover, both when talking with other and probably when thinking internally. How much is racism is the tough part to figure. For many there are probably multiple overlapping reasons, including racism to some degree.
On the left there is a sudden tendency by the presidents loyalists to attribute racism to any disagreement with the Obama administration. So you get the absurd situation of Democratic loyalists calling hard progressive racists because the progressive think Obama isn't going far enough.
