I can barely believe that you're arguing that non-muslims aren't being persecuted by the Iranian authorities. Christians and Jews are ignored for the most part because they're almost invisible in Iran nowadays. Other religions, including Sunni muslims, are subject to various degrees of persecution.
Don't get me wrong, I don't see Iran as the shining example for Muslims lands, I'm stating that even in a land as Iran, the civil rights of Jews and Christians are defended by the law. I missed the nuance there, myself.
