9/11 was named Patriot's Day shortly after the attacks occurred...?

I hope I'm not offending anybody - that is not my intention. I honestly do not understand why 9/11 is called Patriot's Day. Most of the people who died that day were at work, and except for the people at the Pentagon, the jobs didn't have much to do with patriotic activity. They were mostly civilians who went to work because they had families to take care of, bills to pay, etc. Some of the people were probably patriotic, but people from other countries died here that day, too. Does the title Patriot's Day seem a little misleading to anybody else? I've heard 9/11 compared to Pearl Harbor Day, D-Day, Veteran's Day and Memorial Day, but 9/11 was an attack on - mostly - civilians. I don't have any idea what else to call 9/11, but Patriot's Day just doesn't seem to fit. Again, I hope nobody is insulted by this question.
