Small rant here. I greatly dislike the term “Islamist” as it mis-states the perpetrator and cause, reducing them to an admirer or interested party as opposed to what they truly are, an adherant of ISLAM. Instead of calling them “Islamist” they should be correctly identified as “Moslem Terrorists”, “Islamic Terrorists” or simply Moslems and point out that they are following the written intent of the author of their holy book.
I use the term islamist from my reading of “Pan-Islamism” in the 1968 Encyclopaedia Britinnica.
It fits.
