A lot of this is agitprop and we are not getting the full story.
Live Thread: Egypt Revolution 2.1 The Ikwhan Strikes Back: Deadly “Day of Rejection”
http://www.freerepublic.com/focus/f-news/3039526/posts
Day of Rage - General protest against X for X doing something bad against Islam or Arab society.
Day of Resistance - Violent protest to vent anger at X.
Day of NAKBA - The catastrophe of Israel's creation in 1948.
Day of KAKSA - The setback of the Israeli victory in the 1967 Six Day War.
Day or Period of HUDNA - A fake truce as long as the Islamic side is weak in any conflict with a non-Muslim.
Period of Resistance - Term used by Hezbollah in Southern Lebanon to justify their military takeover of all of southern Lebanon, supposedly to oppose the Israeli occupation of southern Lebanon which ended in 2000.
The resistance continues against Israel...forever until she leaves the “Occupied Territories...wait which ones? 1967, 1956, 1948, 1937, 1917..OK, I get it ALL OF ISRAEL.
Partner [for peace] - a ploy where the Muslim Arab pretends to negotiate in good faith but really planning to kill the Infidel ASAP. Used brilliantly by Arafart and Abu Mazen.
“Two-State solution” - Current term used to establish an PLO state next to Israel in order to speed up Israel's demise. This great solution put forward by the “I don't have a clue” Americans is really a rehash of the UN 1947 Partition for Palestine” plan which, of course was rejected by the Arabs (no such thing yet as Palestinians).
The Arab grievance is always a high priority in their lives because they have nothing else except miserable, lowly lives and terminal hemmroids. They're always revolting and they smell like it too.
So, you see, they never really need and official reason for violence and mayhem, it's all in the playbook, Koran.
