I saw that, too. But notice they said "Arab regimes" and "Iran's Arab-parast President". I've seen anti-mullah Iranians refer to the leadership as "Arabs" or "Arabist" as a term of derision and contempt.
You are correct, and arab-parast means arab worshiping. Iranians think of of arabs as invaders and pillagers of their land and culture. Nothing riles Iranians more than being called arabs.
