The Zoroastrians who became Gujarati Parsis made an agreement with a Hindu ruler to be allowed in as refugees, as long as they do not proselytize or allow conversions to Zoroastrianism. Previously, it was not a strict ethno-religion.

You are right, but there is also the net positive Hindus feel about Zoroastrians. The (probably made up) story that I heard was that when the Zoroastrians (Parsi as they are called in India) came to Indian land escaping persecution from Islam, an emissary was sent by the Indian king of the state of modern day Gujarat with a bowl filled to the brim with milk - to indicate that the kingdom was already filled and there was no space for new people. The Parsi leader added a pinch of sugar to the milk to indicate - there is still space for us, and we can sweeten the milk too. This story sums up how as a minority Parsi's have come to occupy an important space in Hindu dominated India. They were provided a safe space, and in return for it they made a net positive contribution to India.
