First FALSE statement:
They hate freedom
I know, to an American freedom is everything. It contains so much that it has become a hollow, pathetic phrase to some point.
But why should muslims hate freedom?
Let us be more precise what they HATE:
They hate our lax treatment of tradition and our own christian values
Not only do some contradict their belief, but they have problems with the absence of god in everyday life.
Most muslim nations are still ruled by a mix of religion and politics, while western nations much more cut the power of the church in political terms.
The ongoing support for Israel, a long-time enemy
This makes the USA a primary target, and some countries like Germany relatively secure. Germans killed Jews in WW2, and they did not participate in the Iraq war.
The hate against Jews has a LONG tradition. Several wars... the Palestinians are still in a constant struggle with the Israeli.
The common enemy
Muslim nations are backward in many regards today, technologically and socially. Envy might also play a major role, and someone is always to blame. Why not blame the evil, godless westerners.
These are the reasons IMO. A bit more complex than "they hate freedom!!!"...
I still despise terrorists and cannot understand them. If this is their way to improve their society, they will still be at the beginning of the modern age while the Americans already left America for Alpha Centauri.
A clash of cultures.
Terrorists are themselves basically modern day equivalents of the Ismaelite Assassins... they were always seen as mislead, but todays miserable situation in many muslim countries makes radicals supposedly more attractive to the people.
The sad thing is, even rich and educated muslims from say Saudi Arabia are often fanatical hatemongers. The royal family of Saudi Arabia is in particular interesting, as it is greatly divided in their view of the Western world:
Some outright despise western lifestyle, others accept is as long as they can make profit with westerners and oil, others are open to westenr lifestyle.
The sad thing is, the radical part is always the one causing all the trouble.
