At best this is one form of Islam replacing another, a temporary modification or moderation means nothing as Islamic controlled states tend to eventually revert back to their feral state when troubles come, and they will. Islam is a non-reformable political ideology. How would you reform communism? The growing voices within Iran to listen to are those that wish to drive Islam out of Persian society altogether.
Iranians are the historical victims of conquest and the Islamic/Arabic conquest has brought nothing good. Support those who want to free themselves and their nation from Islamic control.
