He motormouthed his way through the interview, and doesn't address correction or criticism so much as dismiss them as simply being typical liberal media takes on the matter, and therefore obviously wrong.
He shows no sophistication or nuance in his understanding of trade, economics and corporate behaviour; everything is perceived simply through his populist, nationalist, "clash of cultures" worldview, with his apparent love of capitalism mixed up with his somewhat contradictory distrust of corporate elites for making too much money. (The Catholic influence is pretty clear - but only in so far as identifying a problem with capitalist excess. There's not much sign that accepts the simple proposition that is also Catholic: that it is an appropriate role of government to directly intervene in those excesses for the greater good. Instead, he just seems to think that if all globalism stops, all companies will naturally behave better.)
In short, as lots of people have been saying about the New Yorker decision - it's ridiculous to think we don't know enough about his views and politics already, or that he is ever amenable to genuine, detailed debate. He has his views; he makes his living by being a polemicist; and he dog whistles for support from the obnoxious and racist alt.right continually.
There is no point in his coming to a Left leaning festival, other than to invite an unedifying shouting match.
Update:
I've gone back over some of my past posts about Bannon.
Even if I do say so myself, I nailed it pretty good in this one.
And from another post, look at the way he was the source of the Trump quasi-fascist "fake news" meme that has killed hope of rational debate with Trump cultists:
But it's clear that a huge part of the problem is the people around him - particularly the unhealthy looking Stephen Bannon, who is obviously either behind, or completely supportive of, Trump's paranoia with how the media presents him. Here he is, quoted by the NYT:The guy has ideas, sure: but they are obnoxious and merely asserted - it is not as if they are well researched or ever justified with details you can argue about.
“The elite media got it dead wrong, 100 percent dead wrong,” Mr. Bannon said of the election, calling it “a humiliating defeat that they will never wash away, that will always be there.”“The mainstream media has not fired or terminated anyone associated with following our campaign,” Mr. Bannon said. “Look at the Twitter feeds of those people: they were outright activists of the Clinton campaign.” (He did not name specific reporters or editors.)“That’s why you have no power,” Mr. Bannon added. “You were humiliated.”“The media should be embarrassed and humiliated and keep its mouth shut and just listen for a while,”“I want you to quote this,” Mr. Bannon added. “The media here is the opposition party. They don’t understand this country. They still do not understand why Donald Trump is the president of the United States.”Yes, just what you want. An unstable, vindictive culture warrior who won't accept that the Trump victory was, in fact, very narrow, advising a vain, insecure man-child who stumbled into a presidency he didn't really expect.
As such, no matter how much you don't care for Lefties not challenging themselves at literary love ins (or however you want to put it), to invite Bannon to a serious "ideas festival" is too much like the false equivalence of claiming you must have a climate change fake "skeptic" at a science festival or a serious TV discussion in order to say it has given the topic proper coverage.
No, he has shown he does not deserve a mainstream platform to bluster his views again, or to attempt to rehabilitate himself as some sort of misunderstood Mr Reasonable.
Update: amusingly, I see that some of the old characters at Catallaxy thought Bannon did great in that interview. Their reactions are so predictable: if any right wing guy talks over a woman interviewer (especially one from a public broadcaster), they'll think he's fantastic.
