Yes, the primary motive is probably Ameriphobia. We have massive doses of this disease in this country of traitors.
The problem with Islam is that it feeds any hatred there is, and validates it. Islam hates anything that isn’t it. Islam says to destroy the things you hate, which coincide with what Islam despises.

I’ll buy it if they’ll concede that islam is not a religion. It’s a death cult.
Lots of people have mental illnesses—they don’t join the death cult. ISIS is 100% about the cult of islam.
And much of what IS it. Sunnis, Shias, Shias, Alawites, etc. Each of them proclaims the others to be apostates who must be killed.
