Pbjls, 50 seconds! Wow! Do you rent your son out? Because in about another month I have 14 chicks that could use the 50 second treatment!
I think that it is not just the Disney stuff and the impersonalizing of our meat that causes this issue. Most people have resistance to killing programmed into them. This works for us as a species because I do not kill the person who blocked traffic on my way to work today, or the many, many other people who annoy me. (What can I say? I do not suffer fools gladly.) For most people, this resistance to killing carries over to animals. In fact, we often tend to give people who enjoy killing too much the "hairy eyeball," and avoid them.
My mother was born during the Great Depression, and they kept chickens and pigeons so that the family had a protein source handy at all times. My grandfather used to buy a turkey, tie it's feet to the clothesline and cut the head off --that was how they got Thanksgiving dinner. Even though this was how she was raised, my mother will not kill animals, and refuses to have anything to do with the chickens that I raise to eat. She gets upset if I offer to tell her which bird is which, but she never had store bought meat when she was growing up. Of course, as long as I don't let on who is who, she loves to eat my chickens. So I kill and clean the chickens, and my mother brags to her friends about our home grown chickens as long as she doesn't have to do the dirty deed.
I think this is a complicated issue. Many of the people who become upset about slaughtering animals have a genuine, strong emotional reaction. They are not just being weak or ducking a nasty chore. Having someone become sick or causing them to suffer emotional trauma just to get a piece of fried chicken is not right.
The reason that I raise meat birds is I get the pleasure of knowing that my chickens had a really chicken life, and a heavy heart when I send them to the "cone of silence." I know it may sound strange, but both are important parts of the process for me. But, my mother has given me understanding and respect for those who find the process to be too much for them.
