Iranian national chauvinism and sectarianism

The Islamic revolution in Iran never was able--assuming it wanted--to stamp out those elements of Iranian national chauvinism and condescension toward Arabs.  There has been a movement in Iran, under the Khumayni government, to remove Arabic loan words from Persian (they amount to some 30%?).  And in recent months, it seems that Ahmadinejad found his last refuge in stoking the flames of Persian national chauvinism towards Arabs.  He discovered the value of Abu Musa island and the treatment of the Bahrain issue ignores the Arab national identity of the people of Bahrain, regardless of sect.  The matter was settled in that regard.
