do you really think murdering your political opponents is justified?

You don't know your own history. This is EXACTLY how your governments work; you murder that which jeopardizes your 'experiment' otherwise we'd still have Dr. King, we'd still have Malcolm X, we'd still have Kwame Ture. It's only the last hundred and twenty years that the crackers have tried to whip the righteous desire for vengeance out of the denigrated and put-upon subject of empire.
