the tentacles of the persian state…
As a supporter of the Iranian opposition, I’d like to correct you about this description. The Islamic Republic have nothing to do with Persian ethnicity or Iranian nationality. Only 50%-60% of Iranians are Persian, it’s a very ethnically and culturally diverse nation. The Islamic Republic is a theocracy that oppresses the people of Iran. They destroy secularism and minority cultures in favor of Shia-style Islamization.
I’ve heard different answers to this question. Conducting a poll is obviously a hard task to pull of in an authoritarian country, considering the censorship by the state.
A quick search got me to this poll: Article, Archive
So the answer would be that only 15% of the population are pro-theocracy.
