Yourofsky is in BIG trouble if I ever meet him.
(Death by hero worship is no laughing matter.)
Anyways, back on topic ...
I once saw a graph that mapped out four trends from something like 1940-90; Pernicous puberty in girls, sperm count in men (due to the white male patriarchal conspiracy sperm count in women was completely ignored), average dairy consumption and the feeding of estrogen to the dairy herds.
As both dairy consumption and the amount of estrogen pumped into cows soared so did pernicious puberty in girls whilst male sperm counts plummeted.
Since then I've always found worries that soy might make men into nancies more than a little bit funny.
