E.D. Kain tries to get a handle on Loughner:
[T]hese types of unbalanced, violent loners who spout conspiracy theories and sometimes resort to violence are lumped in with the right because of their anti-government streak. This is a mistake. Loughner was devoted to distancing himself from reality. He wanted to create his own reality, and anything that represented authority whether concrete or abstract and that threatened his dreams became suspect. Thus language, religion, government, currency all the building blocks of society and of reality as most of us accept it became things that Loughner wanted to destroy, remake, control.
