Is that "terror"?
Besides, why not prosecute them for their actions, why proscribe the organisation as a terrorist one, while at the same time ignoring groups who commit much more violent offenses (such as the one given) and concentrate on prosecuting "personal responsibility"?
Because if you stir up enough hate some will act on it. You can't hope to control stuff like this by personal responsibility.
