I came across this post by Natasha Chart of change.org via Twitter (thanks, @hyperlocavore). A brief excerpt:

Genital feminization of male humans and animals: This one always gets them where it hurts, but the industrial pesticides used in agriculture are among the class of chemicals that mimics or stimulates estrogenic activity in the body and are linked, or suspected of being linked, to decreased sperm counts and genital abnormalities in male animals up and down the food chain.

If this is a) true for human males, b) reliably verified and c) widely publicized, it's game over. No American man will eat anything but organic produce ever again. I guarantee it!
