Jewish customs do maintain regular circ stats globally - its the non-jewish males that the numbers start to become disproportionate.

Its like the woman who always cuts off the side of her ham before baking it, but not knowing why. When she finally asks her mom about it - her mother explains its because HER baking pan was too small to fit the ham!! So many things we do automatically are because its something that "is just done" and no one ever thinks to question.
