It's a lot to do with the meat business.  It's lobbying to-and passing laws to keep the public ignorant about what they do to animals raised for human consumption.  If the American people really knew-or bothered to know-what they're really eating, they stop.  As it was, there was zero guarantee you weren't eating dog, cat or other meat. Same goes with animal fur; not that I think most meat eaters care.  In my experience, meat eaters know what they're doing is wrong, but they do it anyway, regardless of the lives taken for their pleasure, and the horrific manner in which the poor creatures they allow to be slaughtered are raised, the conditions in which they live and ultimately die.  If meat eaters didn't know it's wrong, they wouldn't get so upset with the messenger when the truth of matter-and their integral part in it-is revealed.   And believe me, the truth is nightmare inducing. How anyone could eat meat or wear fur agonizingly carved off a living, sentient creature is beyond me.
