You've got it all wrong brother, because the Islamic definition of extremism is nowhere near the kuffar/media/govt definiton. Sadly, many muslims have also started using this word when they don't know what it really means.
MWarrior: I've got it all wrong? I haven't expressed any opinions yet!
Let me put it another way: I wish to explain Islam's understanding of the phenomenon known in the West as "Islamic Terrorism". That doesn't mean I agree with it, only that I recognise it as an accepted norm in Western thought.
