I didn’t think the Zoros accepted converts. They seem to believe that everyone is born in the religion he is meant to practice.
it depends — in India the Parsis (descendents of the Zoroastrians who migrated in the 8th century to Gujarat) do not accept converts as that was some kind of deal they made with the Maharajah of the Gujarati kingdom.
Then it became a race thing - you needed to have your dad a Parsi to become a Parsi.
But the Iranis accept converts.
