Adamson's work generally is excellent. I've been following the podcast for about 4--5 years now, and have worked through the entire mainline backlog (I'm now revisiting parts), though I'm still catching up on the Indian and Africana Philosophy track. Very highly recommended.
"Islamic World" replaces several earlier-prevalent terms. Again, Adamson makes the case against several proposed alternatives.
While his reasoning about his world view and consequently the name of the book is sound, he is not establishing a causal relationship between religion and anything outside the realm of philosophy. He argues that this is the best common trait for philosophical work of those people in that era in the region. It's also natural that he sees everything through a philosophical lens.

We don't have to cover it under the same _umbrella_ term. In the clip (around 11:07) he shows the slide again and says "As an American, I am a born marketer". Imagine if we were to apply the same argument with a comparable time frame (important distinction) and call him a Christian European. Maybe being good at marketing does was not one of their traits. This is the missing nuance.

On which point, what specifically is yours?
