I reread the article and pyne doesn't state any identification with any particular oriental culture and about what i know muslims and arabs do you mean by example that the arabs are consider ethnics and muslims are more religious group. I really don't know what else to put
Arabs are loosely defined as anyone who speaks Arabic or is descended from an Arabic-speaking family. Most (but not all) Arabs follow the religion of Islam.
Muslims are the people who follow the religion of Islam. Arabs are an ethnic group.

Arabs and Muslims are often associated with each other because a significant majority of Arabs follow the religion of Islam. However, it is important to understand that Arabs and Muslims are not the same thing.
Arabs are primarily defined by their language, Arabic, and can be ethnically diverse. They can come from various countries and regions, including but not limited to Egypt, Saudi Arabia, Iraq, and Lebanon. While many Arabs are Muslims, there are also Arab Christians, Arab Jews, and people of other faiths within the Arab population.
On the other hand, Muslims are individuals who follow the religion of Islam. Islam is a monotheistic religion with its own set of beliefs, practices, and principles. Muslims can be found across the globe, belonging to various ethnicities and cultural backgrounds. So, it is not accurate to assume that all Muslims are Arab, as there are Muslims from different ethnic groups such as South Asian Muslims, African Muslims, and many others.
In this context, the article you mentioned did not identify any specific association between the writer Pyne and any Oriental culture, including Arabs or Muslims.
