There are not many Egyptians or Iranians around where I live. The last time I remember talking to one for more than few minutes was years ago, in the university cafeteria. A biochemistry student, that I guess would fit your "Iranian talking about their non Muslim days" criteria. Though she'd consider herself Persian, not Iranian.When's the last time you've seen an Egyptian talk about how great Egypt used to be? Or an Iranian talking about their non Muslim days? You'll see western nations who were straight out conquered by Rome still call back to it as almost an honor. But you won't see an Imam in Egypt talking about how bad the country is now and if only they'd have looked back on what Pharaoh did in X situation.
