"His favorite book list is actually rather good, I must say, featuring Orwell’s Animal Farm, Huxley’s Brave New World, Carroll’s Alice in Wonderland and Through the Looking Glass, Kesey’s One Flew over the Cuckoo’s Nest and Hesse’s Siddharta (as Erstausgabe_von_Mein_Kampf well as Marx’ The Communist Manifesto and Hitler’s Mein Kampf). While these are all masterpieces, they have in common that they deal with the topic of reality perception being controlled by higher powers, as well as the possibility of alternate realities. Loughner in his YouTube videos writes about ‘conscience dreams’, and his MySpace is called ‘fallen asleep’. His talk of grammar being controlled by the government calls to mind Foucault.

The inclusion of The Communist Manifesto on this list has been cited by some as proof that Loughner could not be a Tea Party activist, but since the Manifesto deals with the topic of organized revolution more than it does with imposing a state-controlled economy, I find its appearance on the list not so strange. It also seems that Loughner had came in contact with (campus) police a couple of times, so a picture more or less emerges of a troubled adolescent, who reads stuff that’s maybe a few levels too complex for him. But these are exactly the people that you shouldn’t expose to the sort of militant, violent political rhetoric that since Obama’s presidency has been employed by the Tea Party and the Republican right.

The latter point is a good one, I think. The entire psychological structure of the "Tea Party" is rooted in the theme of patriotic armed revolt against an illegitimate tyrant. Violence and the rhetoric of violence is embedded within it. When you do that, someone somewhere will take you seriously.
