Monotheists have no monopoly over discrimination against religious and other minorities. To take just one example, whatever Baha'is face in Iran, it's not comparable to the anti-Muslim pogrom in Gujarat and the state complicity in it and attempt to cover it up: <http://hrw.org/english/docs/2002/04/30/india3885.htm>.
Whatever real grievances Iran's ethnic, religious, sexual, and other minority communities have will be magnified thousands of times, and where real grievances are not enough, imagined ones will be invented to augment them. That's where identity politics -- especially diaspora identity politics -- becomes the most useful to imperialists.
The best known example of this is Washington's use of Hmongs in Viet Nam and Miskitos in Nicaragua. In that sort of campaign, some leftists (e.g., Ward Churchill) and many liberals are known to volunteer enthusiastically.
Ahmadinejad can't prevent that from happening -- and no one can -- but he ought to make efforts not to give any ammunition to imperialists and, where possible, try to do counter-hegemonic diaspora identity politics. He needs to learn from Fidel's and Chavez's attempts to reach out to Black communities in the United States.
