Well, Iranians have their own version of Islam, which, in my quite biased opinion, I tend to say it's better than that of the Arabs. So, probably, nope, they don't like the Caliphates. Religious Iranians insult them for being the wrong kind of Muslims, Secular ones curse them simply for being 'Arabs'. Ask any Wahhabite to tell you stories of how Persian Rafidi Sun worshipping Jews destroyed their beloved caliphates, Abu al-moslem and Al-toosi and all...
Can be say it in easier words? I have no idea :O
