I think you mean the proposed boycott, not the event itself. As for whom religious pressure on it affects: well, why the big deal about airport scanning? Who does it affect? Give them time. You fundamentally misunderstand: the festival isn't being "opted out" of, but rather "squeezed down on" using religious pressure and guilt. Given the history of Zoroastrians in Iran, this should be a warning bell. Yet you belittle criticism directed at those who would eventually work to end the festival, which is not so commendable.
