While I'm not willing to welcome Islam anywhere, since Iran was mentioned, I'll put forth my 2 cents for those interested.
I have distant relatives who live in Iran. Iran's regime is currently very respecting and protecting of the Oriental Orthodox Christian Churches in the country. There is no discrimination with regards to Churches, Christian community centers, Christian-only schools (accredited), and so forth. I don't know about the other countries mentioned in this thread, but Iran is run somewhat differently. I have heard that they do go after Evangelicals for the sole reason that they evangelize to Muslims, and that's pretty much a death sentence by law, so there is the negative.
As an aside, everyone in Iran is classified by religion. If a Christian couple wishes to legally divorce, the court will not handle the case and instead direct them to their respective Church. Only AFTER the Church has approved the divorce and issued a formal letter, the couple can take it to the court to dissolve the marriage. Whereas their court has special processes for Muslims wishing to divorce, those are waived for a Christian carrying a formal divorce approval from their Church (which also refuses to issue the approvals unless it involves adultery, crime, and other types of wrongdoing by either party.)
