The term "freedom fighter" has traditionally been used to refer to those who engage in guerilla warfare against military/government targets in attempts to overthrow totalitarian governments. The term is legitimate whether the revolutionaries are fighting against a left-wing or right-wing regime as long as the targets of the attacks are government/military and not civilian.
Military or paramilitary operations AIMED at civilians should be labeled as terrorism. (Which would mean that Janet Reno qualifies as a terrorist.)
I think if you read my post again you should see that I would never suggest that the scum who planned and executed these attacks were anything but terrorists.
