Re: RSS on their Conversion Assignment!
Discouraged but not unheard off. Why else would Jews in India look like Hindus. Likewise for Parsis.
Parsis in India have been averse to intermarriage so have retained some of their heritage, but one of the reasons why Zoroastrians are so far and few between is because of intermarriage outside of their faith and culture. So i suspect they must have significant Hindu ancestry despite this.
