If you look hard enough a small portion of it still is. Even Iran as much bad press as it gets is really a tell of two different people, one being followers of every tenant of Sharia law, and another very modern and moderate in their faith... some even Christian.
Yeah, Iran is a special place. We should be supporting as we can the Iranians wishing to live in the modern world.
Some are Christian and more, perhaps, are Zoroastrian. We won't know how many of either for as long as they fear to reveal their faith.
