I’ve never actually heard anyone use that line except people in alt-right circles, and I am around a lot of Muslims. It is not a term Muslims use to describe their religion, not that they would describe it differently, just that it is a strange description. It would be like calling Canada “the country of peace”, which I guess is technically true because most countries want to avoid war and promote peace? But does not mean their military is non-violent.
The line is clearly used for the intent of creating a false contrast to make some made up point about hypocrisy.
Also as the other commenter pointed out, you are making a critique about the middle East, everyone agrees the middle East is dysfunctional.
