As far as numbers go, who wants to be one of teeming millions, living in abject poverty, misery and illiteracy, like millions of unfortunate people live around the world. In fact, an explosion in population gives birth to a million ills like poverty, malnutrition, disease, illiteracy, etc., etc. In fact, in this world where we are surrounded by so many powerful cultural and religious forces, reforms, if anything, would lead to our annihilation. It is our exclusivity that has helped us survive. It is not the 'size' that matters when it comes to survival, it is the 'strength' and 'power' of one's beliefs and ideas that go into making up a community, that is aware of its place and role in society.
Every religion has a time and purpose.
So does Zoroastrianism. And that's all that matters. We may be few, but still we shine in all walks of life. However poor, a Zoroastrian home is always clean. Our people do not suffer from acute malnutrition and starvation like countless others do all, over the world everyday.
