Muslim here, that sounds absurd. In fact one of my biggest annoyances is when people view all Muslims around the world as single entity. Every stupid trait of every Muslim majority culture gets blamed on entire Muslim world.
I find it absurd too, but it is often how it is phrased in English-language discourse, even in Dutch discourse the anti-Islām branch phrases it as such: the language suggests that one can identify a “Muslim” by some kind of physical phænotype of his body.
The difference is that in general in Dutch discourse, such statements are considered racist or betraying such a mentality, and frequently protested, but, in English-language literature, even the “left” that claims to champion the causes of all these “races” and “religions” still very often writes in a way that betrays a mentality that some religions and countries are “races” and others are not.
I have noticed in English-language discourse that often, shall-we-call-it, “non-white countries” are “races” but “white countries” are “nations”.
Also, Christianity and Judaïsm are religions, but Islām is a race.
Explain me that.
