Iranian refugees are probably young people who aren’t Muslim and who probably hate Islam
That’s not what you’re going to get.
I know evidence is hard to come by in authoritarian Iran, but there is evidence that the majority of young people - people under 35 make up half of the population - are Muslim in name only. They don't go to mosque. They hate the government. They are secular as a result of living under years of an Islamic government that is a combination of harshly religious, incompetent and cruel. I know its not easy to predict, but Iran is probably more like East Europe than Afghanistan or Syria.
