My jokes is that a fundamentalist is somebody who doesn't understand the fundamentals of their faith.
Have you read the Quran?
They just use religion as an excuse to be ********
The general fundamentalist mindset is that of the besieged noble warrior, who is doing immoral things for the highest moral cause, against a percieved immoral enemy and is thus in their localized worldview and political conditions super-moral and the greatest examplar of the faith/belief/nation in the group.
I would argue the contrary. The extremes are the ones that take it seriously.
They tend to pick bits and pieces they like, and often take them out of context. Plus they can always have their own revelations.
