ELI5 Why we say "Islamic" extremism instead of "Muslim" extremism

If we're talking about extremist Jews, we wouldn't say "Judaic extremism" right?

Typically, "Islam" refers to the religion, and "Muslim" to the people who follow Islam.  "Islamic" is used for anything that is part of the larger culture of Islam- Islamic art, Islamic Music, Islamic Prayers....and so on. 

So we say "Islamic extremeISM" and "Muslim ExtremeIST"
