It should be pointed out...the fire festival has been around long before Christianity or Islam or even the Roman Empire, and it’s the one Iranian festive occasion that the Mullahs can’t cancel out or control.
This may sound really simplistic but why don’t people insist on being called Persian? A theocracy is almost impossible to break loose but Persian heritage pre dates Islam by thousands of years. Sometimes a word,a symbol or even a flag can unite people.
Iranian Burning Man.
