I must ask though that if Zoroastrionism is given equal status in India or is it still not allowed to be preached openly?
Zorastrianism is allowed to be preached openly. They can set up temples where they like, but their towers of silence are hard to come by - I have seen one in Bangalore and Mumbai.
Zorastrians are one of the richest communities and are very well liked and respected. (Tata, Godrej etc. etc. are all Parsis).
