Terrorist, Who Are You?

I was quite young when I realised that a terrorist to one is a freedom fighter to another. Is Ariel Sharon a terrorist? How about Sheikh Ahmed Yassin, was he a terrorist? You probably said 'Yes' for one and 'No' for the other. But what criteria did you base yourself on, if anything more than mere acquired conviction? People that were deemed freedom fighters by some were routinely referred to as terrorists by the Lesotho regime of Leabua Jonathan. But the dilemma goes even beyond such ideologically tainted identification, into the very linguistic realm of the terrible word, terrosist. Terrorist, who are you?
