I decided to look up in the thesarus the Synonyms for terrorism. Several entries came up and while I don't agree with all of them, this one seemed most appropriate.
Some other terms for terrorism meaning disorder are:
anarchism, anarchy, chaos, commotion, disorganization, disturbance, fight, insurrection, lawlessness, mayhem, misrule, mob rule, quarrel, rebellion, revolution, strike, terrorism, turbulence, turmoil, unrest, unruliness, uproar
I did edit this list so it was not quite so long. But it is intresting to note that rebellion and revolution both pop up. Your goal is to overthow a goverment that is corrupt, and you don't have an army to battle theirs due to numbers. A resistance using violence to any goverment operation would be cosidered terroristict by the goverment. If you are small group of people trying to fight back against the evil goverment you have no choice but to do the things that terrorists would do. In open battle you would be slaughtered. Your goal is not to insight terror in the masses however so it all come down to symantecs. Is there a better word? I'm not quite sure. Your tactics would be the same, and you would scare people reguardless of your intent.
