It is not an excuse if the guy is ready to throw himself and an airplane into a building for it. That means the guy is pretty sincere. The word you are looking for is motive.
The fact that you do not find their motives "reasonable" intrigues me. Is it their methods you disagree with, or their grievances?
If you think their grievances are not legitimate, does it change when you substitute "gold rush" for "oil rush" and "red skin" for "rag head"?
(By the way I'm not thrilled about getting bombed. I almost lost a friend in Boston.)
