can anyone like me just join zoroastrianism?

i want to know if it is possible if i can join Zoroastrianism, cause yeah...i am learning about it, but i don't know if i can just join it, or if i have to go into some sort of ritual or even if i can never join cause i wasn't born into it.

You don't need a church/temple/mosque to join any religion. Only the mindset and their book or teachings.

It is not a club that you join. Learn to recognize it for what it is and think about it in a proper and accurate manner and you will be further along in your approach of Zoroastrianism than you think.

I know they don't proselytize, and I don't know if they even accept converts. In order to be a part of their religion, you would have to learn a new language and move there.

You can join Zorastrianism only by marrying a Zoroastrian but you will never be considered a Parsi. Earlier they did not accept any Non-Parsi! There is still a heated debate between Parsis whether to allow people into the faith or not.

I think you have to be born into it. I know there are articles on line pushing for adherents to marry inside the faith so the religion can be 'saved'. This tends to suggest that they will only survive by breeding more Zoroastrians.
