Reading Comprehension

The Forward did an interview with Max Blumenthal in which, among other things, they ask him a question about why he thinks he gets a bigger response from videos he makes than from articles he writes. He replies:

I wrote in 2005 a piece on the College Republican National Convention, and I asked participants the same question. While the reaction was immense, it wasn’t the same. I think for so many people, reading is just such a rigorous mental exercise; they just can’t handle it. They respond much more to my videos. That’s partly why I produced it, to break out of the liberal intellectual bubble that I’ve been working in and that audience that I’ve been writing for. And I think I’ve really broken through.

In short, he's not sure, but he does think that video reaches a broader audience than he's able to reach with print. Thus, one reason he makes videos is to reach an audience outside of the "liberal intellectual bubble" comprised of the print outlets he's written for. Jamie Kirchick, guest-blogging for Andrew, somehow manages to completely misconstrue this:

Portraying himself as a truth-telling hero for capturing the wignuttery of Christian Zionists, this part of the interview is particularly laughable:

That’s partly why I produced it, to break out of the liberal intellectual bubble that I’ve been working in and that audience that I’ve been writing for. And I think I’ve really broken through.

Because as we all know The Nation and The Huffington Post are bastions of objectivity and politically diverse readerships.

What's the sarcasm for here? I'm baffled.
