Out of all of the sects in the world, we notice an uncanny coincidence: the overwhelming majority just happen to choose the one that their parents belong to. Not the sect that has the best evidence in its favour, the best miracles, the best moral code, the best cathedral, the best stained glass, the best music: when it comes to choosing from the smorgasbord of available religions, their potential virtues seem to count for nothing, compared to the matter of heredity. --Richard Dawkins
Almost every religious person will tell you that their religion is the most logical, the most accurate, and has the best moral code. And yet the great majority of them were born into their religion and hardly considered any of the others. And a majority of the ones who picked a religion other than their parents', picked the one belonging to most people who live near them. It's as rare to find someone in Alabama who decided that Zoroastrianism is correct as it is to find a Bantu tribesman who decided that Judaism is true.
