Austin Plane Bomber Joe Stack a Left-wing extremist?

Im just waiting patiently for the left-wing media to begin labeling the sick nutcase who flew his plane into the IRS building today as a “right-wing” extremist.  Remarkably, this guy left his manifesto, for all of us to read online.  At the end he cites the communist creed, and mocks capitalism.  Do you think maybe he was a left-wing extremist?  I wonder how this will be spun.
