I have decided to stop referring to myself as a "Zoroastrian" and instead decided to refer to myself as a "Mithraist".
Besides the fact that all my Western friends find Mithraism far more attractive and adaptable to a modern society than Zoroastrianism, it also once and for all removes at least me from any conflicts with Parsi isolationists (a pathetic conflict which I have decided to not fight anymore, just let the isolationists kill themselves as a community, I could not care less, I only care about cosmopolitan people interested in Iranian philosophy anyway).
It doesn't change my relationship to Zoroastrianism in general. And Ushta has always been open to both "Zoroastrians", "Mazdaists" and "Mithraists".
It's just that my change of label makes it easier for people to understand where I'm at, and also makes them far more interested and even engaged.
We even started a Swedish Mithraist community last week, founded by people who love to call themselves Mithraists but not interested in the label of Zoroastrians.
