The anti-Arab racism of Persians can be as strong as Islamic fervor. You doubt that racial prejudice is a force to be reckoned with?
That does not mean they do not want to change their policies towards non-Muslims.
Like I said before, when Israel strikes they will unite anyway and nothing in Iran will slow down Islam in the West. If us and Europe do not end Muslim immigration it is just a matter of time until they takeover.
Wishful thinking with Muslims is part of the reason the problem has now reached our backyard.
