Self Defense = Terrorism
According to supporters of Hamas, self-defense is terrorism. Stopping missile barrages aimed at innocent civilians is terrorism. Blocking Palestinian snipers from shooting at Israeli owned vehicles is terrorism. Stopping the flow of suicide bombers by establishing checkpoints is terrorism.
From the picture caption:
Women Hamas supporters carry placards with Arabic words that reads 'The siege is terrorist,' during a protest against the Israeli blockade of the Gaza Strip, in the southern port city of Sidon, Lebanon, Sunday April 20, 2008.
Everyone and anyone who refuses to convert, submit, or die is a terrorist.
