So, radical muslims scream "death to America/Israel" & this article blames their attitude on: "...  strongest remaining force that propels the Islamic State is the Islamophobia of Trump and his European counterparts," is akin to saying street thugs will be less active if we don't mention their threats & crimes - instead the writer advises us to just duck & cover.
 I'd call that misguided PC paralysis ... or worse.
 A Declaration of War on isis is past due. This isn't merely crime .... it is war.
Careful scrutiny of mosques & suspected radicals by police as well as mobilization of our military would be a better way to protect Americans & prevent future attacks.  Of course careful scrutiny of immigrant applications from muslim countries makes sense.
Intolerance of threats to U.S. citizens is not a vice, it is a requirement.
