Okay, so here's the deal:
Bannon shot his mouth off at some point and made some grandiose claims about his goals. There's no particular reason we should believe them, and no particular reason we should think he's capable of those goals even if he does actually hold them, rather than being something he said to sound cool at a party.
But, if we accept for the moment that Bannon really is going to destroy the state by manipulating the media, and that we should take seriously for just one second that he might be capable of that, we find immediate direct evidence that he is in fact not capable of directing a secret conspiracy to manipulate the media after all: because he told people he was going to do it, got quoted by the media, and ended up in the crosshairs of people like you, who are now presumably going to be watching his sinister schemes and warning other people.
