Most Arabs are Muslim, but some are also Christian, Jewish (yes, Jewish Arabs exist), Druze, Buddhist and of other religions.

Arabs have a darker toned skin and speak the Arabic language. Many languages have borrowed words from Arabic, such as the English language for example. Not all Arabs wear turbans, the keffiyeh, or are "ragheads", and those types of attires really depend on the nationality of the Arab wearing or not wearing them, and what part of the world they are located in.
The "war on terror" dates back to the 20th century, and how western powers were dividing and partitioning the land and nations to fit their needs and requirements. It also refers to Israeli occupation and oppression of Palestinian Arab and Syrian lands. The Arabs rarely will strike back as a form of resistance to their lands being pillaged and occupied and their innocent families being killed. Arabs do not forget history, as they are a very historical people.
