The message is mainly disgust for the nanny state. The acts of terrorism are really only the destruction of buildings and a few specific assassinations. While talking about how justified such activities are is entirely subjective, there were no points where 'civilians' were flagrantly killed as collateral damage and certainly not as targets directly. That would be the shining difference in my eyes.
Too add another log to the fire, if the terminology existed with the same subtext as now, I imagine the founding fathers might have been labeled terrorists. The term, of course, is used now to elicit the notion that there exists something from which people are defenseless and need protection, so that they might trade a little freedom for a little perceived safety.
