"Islamist was purposely coined in order to make links between terrorists and normal people."

Who coined the term and definition? Source?

The term started out innocently enough in articles 1993-2003, mostly denoting political Islam.

Then came the series of articles and diatribes in the press, notably one in Newsweek by a Hayri Abaza, Is it Islamic or Islamist ? (10-22-10)
The use of Islamist for the radical, extremists was endorsed, but Abaza also pointed out that the public would be confused, not grasping (his and others) distinction between Islamic and Islamist.

Perhaps radical should be added as a modifier; radical Islamist.
