Actually, I agree with both of you, in this regard: OF COURSE white people can be terrorists. But, I worded the topic that way partly because of what you said 100Proof: the American media almost always brushes off such acts as merely the work of a lone deluded individual, with little or no mention of his ethnicity or his religion -- as long as the fellow is white. And they do not link (usually) his actions with his ethnicity or his religion. To say that "most terror groups and terrorist use Islam as an excuse to cause their mayhem" is proof of what I am saying, since that is just not the case. I mean, sol, you yourself gave many examples of other terrorist groups in Europe and the US in your post. The unspoken assumptions always seem to be that "white means right and normal, non-white, not so much" and "if you are The Other, you must be a terrorist, but if you are white, well, there must some other logical explanation for your actions".
With the huge exception of what happened on 9/11, how many other terrorist attacks that occurred in the United States were carried out by non-whites? Who commits the majority of violent crimes in the US, and who are their victims? The answers: practically none, young white males, and mainly other whites. Yet we don't go around regarding every young white male with suspicion, or single them out for special searches, etc. at airports ONLY BECAUSE of what they look like...the other name for which is "profiling".
Let's pretend that instead of being a military base, Fort Hood was a bank. If someone who worked at Fort Hood Savings & Loan had gone to work, pulled out a gun, and shot up the place, what would we have immediately called it? We would have called it "a workplace shooting". Well, the man who shot up Fort Hood did so at his place of work -- he was a soldier, after all, and killing people is what soldiers do for a living -- so why is the one just called a "workplace shooting" and the other called "an act of terrorism by an Islamic extremist"? Why is any negative act committed by a person who happens to be of Arab descent, or Muslim, or both, almost always automatically labeled an act of terror, while similar or even worse acts committed by a person who happens not to be of Arab descent, etc., are not? It's this dichotomy that I am speaking out against; the title of this thread reflects the impression given by the media most of the time when such negativity goes down in the U.S.
