USDA is inherently biased toward animal farming, and the first source I linked was a scientific study. But I'm not necessarily denying what USDA says. Holding a bias doesn't automatically make something untrue. You didn't quote anything they said, you made some hasty calculations based on their statistics, which seemed to overlook the distinction between male calves and female calves. You used this to make a statement that I never disagreed with, because I was making a different one. (One could call that a strawman fallacy).

Humane League is an animal welfare organisation. Of course they're going to focus on the most ethically unsound aspects of animal farming, since that's their purpose, but nothing they said was false. They did acknowledge that some male calves in the dairy industry are raised for beef, but that most are killed for veal.
