It's the new, post Islamic revolution Iranians who are objecting.
The pre-Islamic Persians acutally gave Jews and others rights in the process of global empire building (though this is debated : http://en.wikipedia.org/wiki/Cyrus_Cylinder).
Unlike Saudi Arabia and other arab states, Jews, Christians and other faiths live in Iran and even have their rights protected by the constitution (though, in practice, there is significant prejudice). There are Synagogues, churches etc. in Iran - you won't find a Synagoge in Bharain, Saudi etc. Of course, the right re: gender equality and sexual orientation are strictly in accordance with Islamic law (i.e. wofeful).
Please put the ownership of this objection staright at the feet of the Islamic government, not the Persian population who are from a wide background and many of which are struggling to achieve a change of government.
