The intertubes are screeching with right wingers insisting that despite his obvious mental problems, anti-government rhetoric and Paulite goldbug obsessions, the fact that he cited "To Kill A Mockingbird" "The Communist Manifesto" and "Main Kampf" means that Jared Loughner is a left winger.(As always with semi-literate diggles, apply [sic]s as needed, because I didn't bother checking)
Let's just say that we don't really know much right now and anything's possible, but the fact that he shot a Democratic congresswoman in the head argues just a little bit against that interpretation. It's not as if there aren't any right wingers in Arizona.
Digby is of course one of the most absolutely incompetent writers in the world, completely independent of her status as one of the most absolutely incompetent thinkers in the world, but I like how she implicitly poo-poohs, here, the suggestion that "despite his obvious mental problems...Jared Loughner is a left winger." Deliberate? Or the result of shit writing? Who can tell?
The idea that hating a democrat enough to try to kill her makes you a "right winger" is of course too ludicrous to even discuss. Barring unforeseen developments after the collapse of civilization, I will never kill a human being as long as I live, but the dems piss me off at least as much, often more than, the repubs. I don't think I'm exactly a left winger, but I am certainly not a right winger. However those useless terms happen to be defined at this moment.
As I've said before, being a partisan hack makes you completely unable to understand why anybody does anything, let alone anything else in the world. When everything has to fit into a demsaregood rethugsarevil mold, you have to do a lot of awkward shoving and cramming.
(As far as what she's responding to, I also love the definition of identity based on commodities--in this case books--consumed.)
