Ed -- I can assure you that your 4th paragraph is incorrect. Trust me on that.
There's a longer response to the rest, which I do not have time for at the moment, but it is the central question about right-wing politics and right-wing media: does the audience program the network or does the network program the audience?
I'd argue it's the former, but it's a long argument and not straightforward. So, later.
all best -je
