Nordic, I went back to my old political science books last night to re-check a few facts re: Islamism.
It's basically stems from the 1970's political movement in Iran, so you're incorrect in claiming it is much older.
Ayatollah Khomeney is a central figure in the creation of Islamism. He penned several of the ideologies that are central to Islamism today.
You could claim this is all semantics though. But facts are facts.

You're correct however, and this is much more critical IMO, when you point out the fact that one of the main principles of Islamism is to become global, it is aggressive.
This is something undeniable.
Islamism is totalitarian in that the clergyship is considered to fit to lead and decide how the rest of the society should be run.
And then of course the whole world is suppposed to become Muslim. However, Khomeney advises against using "bad" methods fighting the infidels.
But world domination is a goal.
Fact is, Islamism came about as an reaction to what many fundie Muslims saw as a secular movement in Islam countries.
If jaguar would actually take the time to learn about the facts of Islamism, and not just listen to either racists or cultural apologists, she might just be able to see that Islamism is in fact an antagonist to Democracy (as Robert Dahl would put it).
