Hey, now THAT'S better stuff!
Regarding bias and the cutting-off of funding, I see it differently. To me, of critical importance is the nature of the bias, or the dimension in which the bias exists, not necessarily its degree, but its kind (as an aside, I would disagree with you about the degree of bias as well, I think it is every bit the equal of that exhibited by redneck radio).
The dimension in which the bias manifests appears to me to be just as you said--the POLITICAL dimension. Both MPR and NPR exhibit political bias in favor of the general platform of the federal Democratic party, rather than exhibiting bias in any other dimension, such as social, economic, or philosophical.
This alignment in favor of a particular political party, supported by the receipt of public benefits, is tantamount to the coercion of support for the federal Democratic party itself. I don't want to get too deeply into the constitutionality of it, but if Congress undertakes to support one party by allocating thereto public monies that are coerced through taxation, it is probably legally required to similarly support other registered parties.
The argument is not an obscure one, legally speaking--it would be the fact of bias for the party platform that would be the most difficult thing to prove to the required standard.
More later, gotta go.
