I'm saying FOX may have played some part but its not the principal part. It didn't cause its spread, it probably helped it but I don't think by any great measure. And your statement about the similarities between the two parties is laughably false. You can point to certain examples or bemoan the lack of a "real left" but 2013 democrats are not 1994 republicans. (Look at the party platforms).
And I don't think we're ever going to come to agreement on your desire for some sort of state media or a not-for-profit, elite dictated media. I disagree completely. And I'd love for examples besides the BBC (who does have a status quo, liberal, pro-EU/internationalist bias).
