Arab isn't a nationality. That's what you Israelis want the world to think so you can use your support of "Palestine never exisited" and "Palestinians are arabs so they can go live in any arab land". When you say Arab is a nationality that's like saying ENGLISH is nationality or being Hispanic is a nationality. Arab is an ethnicity and a culture, food, music, arts and language. Many Arabs come from different religious backgrounds. Judaism has connection to the mideast. That's like denying christianity's connection to the mideast. I don't know what "studies" you are reading but Professor Shlomo Sand is an expert on it. Through his research he clearly shows that there was NO DIASPORA and that most jews today are coverts. He also states that the Palestinians are the original jews. Islam came 700 years after christianity. It probably reach palestine in the mid 7th century. What religion were these "arabs" before Islam reached?
