No, to all of this. Talking about the largest fraud scheme in the history of the midwest without taking on all of Washington corruption doesn't make you a "gish gallop" or "Banon's flood" (whatever that is). In fact, it's kind of the opposite of a gish gallop. It's a single coherent argument. If you can rebut it, do so.

A critical part of media literacy is not just evaluating a piece of work at face value, but considering who wrote it, why they wrote it, why they wrote it now, what they didn't write etc. The article itself is actually not really interesting, but why this person wrote this article now is interesting.
"the history of the midwest" seems awfully specific and easy to redefine as required.
That being said, it was a fairly interesting article about fraud in general, but if this is the only fraud article he wrote, why is that? There's lots of public frauds going on right now, is he going to write about them next?
