@layman,
I read the TPM piece as well, and also was struck by the categorical denial that there was any evidence of politically biased decision making at all, and that all such allegations are false or built on fallacies. They're a little less clear about the span of their allegations - do they include the organized whitewashing of Clinton ?
This flies in the face of observable facts and common sense. The suggestion that modern media is structurally incapable of detecting lies by public officials looks quite unfounded and contrary to other observable facts. However, it is
indeed a likely logical necessity for their categorical denials of facts already reported.
It is interesting to me to observe these categorical denials and the somewhat related tendencies of posters here to reduce any contrary opinion to extreme cases, denying any possible qualification of their arguments. Truth human nature and the world are in fact far more complex and inconsistent than they will allow.
