Since the December 5 coup, the Fijian blogosphere has sprouted a network of bloggers opposed to the military regime. One of them - Fijian Black, of Good Men (And Women) Doing Something - is currently promoting a silent protest against the coup, the form of a "day of inaction" on May 1st. It may not amount to anything - these sorts of protests usually don't - but even such minor signs of opposition are intolerable in the military's eyes, and so now they are trying to hunt down the pseudonymous blogger, presumably so they can subject them to the same treatment meted out to their other critics.
When a regime suppresses dissent, it is generally a sign that they do not believe they can win the argument on its own merits. When they're reaching as far down the pecking order as anonymous bloggers, then its clear that they have no arguments other than brute force. The Fijian military's actions speak to its own fundamental illegitimacy.
