It's no secret that the Iranian government doesn't like Americans at all. They burn American flags all the time and chant death to America. The government it appears expects all Iranians to hate Americans. Should they suspect that you don't then you might be jailed. How would they know? Easy. http://www.theguardian.com/world/20...-seize-clothes-featuring-us-and-british-flags I wonder if they also strip and arrest anyone wearing clothes imprinted with "satanic symbols."
