Explain that to me. Under law passed under the Bush administration and carried on under the Obama administration terrorism is defined as:
The calculated use of unlawful violence or threat of unlawful violence to inculcate fear; intended to coerce or to intimidate governments or societies in the pursuit of goals that are generally political, religious or ideological.
Now it's not that I agree with the above definition but as it stands the flying of the plane into the IRS building was clearly a violent act, intended on instilling fear with a generally political/ideological goal (the IRS sucks).
The ONLY reason that I can see that this is not being called terrorism is because the person who committed this act was a white christian male. Lets keep it real. If the man was a US citizen named, Abdul and had a beard, there would be extensive talk about what terror cell he must have belonged to.
