I disagree with this particular wording. Americans tend to conflate Arab and Muslim. Not all Arabs are Muslims, although this is increasingly true as Christian Arabs flee the Middle East.
True Arab Fascism exists. It's known as the Baath Party and various offshoots. It's national socialism, with the "nation" in question being "the Arab nation." Some of its founders and major supporters thru the years have been Christian Arabs. It's all Arabs against other nations. It is by nature secular, although when it gets in trouble it's perfectly willing to haul in Islam for cover, just as the atheist Stalin was willing to angle for support during WWII by allowing greater freedom to the Church.
Al Qaeda, OTOH, is Muslim Fascism. It's all (true) Muslims against all infidels and backsliding Muslims.
The relation between Baathism (Arab Fascism) and Al Qaeda (Muslim Fascism) is thus quite remarkably similar to that between Nazism (national socialism for the German people) and Communism (international socialism where the entire proletariat throughout the world lines up against its exploiters).
