Whenever there is injustice, there are people fighting it with every possible means. We have seen it so many times before: the oppressed rise up, the oppressor dehumanizes them calling them such names as "terrorists", "saboteurs", "death loving" extremists... It is only normal that the oppressor will always lie to justify his actions and its crimes.
What is different in the case of Palestine, is that the Israeli regime has built an effective media and communications networks and campaigns to distort the image of the Palestinian resistance, and that a large portion of the world has believed the Israeli line and hence adopted it.
It is our duty to remember and remind the world that the Palestinian freedom fighter is a man, a woman, like any other. He loves his family. She loves her country. They seek a better future. They are willing to sacrifice everything for the sake of justice and freedom. They waited for the world to lift the blatant injustice that has befallen them since 1948. They expected the world to understand when they took up arms to lift this injustice themselves.
Now, they don't care what anyone else calls them. They do not seek anyone's permission, just like any resistance movement. They believe that their cause will be triumphant because it is a cause for justice and humanity. They are merely fulfilling their duty to make the day of justice in Palestine come sooner. So should we.
