Zoroastrianism isn't typically a conversion religion, nor is Yazidism, one of the indigenous religions of the Kurdish peoples.

I suspect this "Yasna association" and their placement of a Reuters article are both efforts by Kurdish nationalists to draw members to their cause. In this case, people who happen to have some negative feelings about Islam after the recent series of conflicts might find a fused religious-nationalist appeal more interesting than a nationalist appeal alone.

In any case it's hard to see why this is news -- or how it in any way relates to Zoroastrianism as it exists in Iran and India.
