If the government wants to label them as terrorists, then that's exactly why they should be hacking. If people don't remind their governments that they can get pissed off and revolt, they're essentially giving the government the right to infringe on whatever liberties they hold sacred. It doesn't matter if the sites come back up in a few days, or if they were dumb sites to hack, or if they're supporting criminals. Its about saying: Hey there Uncle Sam, we're not just gonna sit here and do nothing while you make more decisions that profit big business and "fight crime" at the cost of our freedoms. We are angry and dissatisfied with your leadership, and if you screw with us we will retaliate and encourage others to stand up too.
