I Lasted three days, threw up every night and finally admitted to myself I couldn't tolerate it.. mind you its not the butchering, I have always helped process our deer etc...
I once told my sister who couldn't understand how we could kill and eat the animals we raise that killing isn't done for the joy, its done for the necessity. We are meat eaters, I would rather raise my animals with kindness and care, knowing where the animal came from and how it was treated then some factory raised animal. Our animals are reverenced and the act is done quickly with as little pain as possible, and thanks are always given for the life taken to sustain us.
I suppose I have more of a problem with folks who have a problem with what we do, questioning how we can do it then with anyone else. Folks are desensitized these days, they go to the store and the meat is neatly packaged, they don't care what the animal went through to get there.
