I agree on some of what you say. However, I disagree with the interpretation of the result. On the surface that veneer is tantalizing, but in actuality it's more damaging than blatant leftists and rightists. Do you recall the Movie "They live". It's like that. Insidious. Pretends to be nice and psychologically it's more sophisticated, but also more believable and people tend to give their pieces more credence with less critical questioning than say a Fox news or MSNBC, because they mask it well.

But as I said in other comments, they're the best available option (to me), but that does not mean they are a good option. so long as you keep your ears open for their biases, they're okay to listen to.
