Lots of people don't really understand where meat comes from. They understand the concept that an animal has to die, but they prefer their meat comming out of a plastic package.

Example: we used to raise our own animals, I knew every single one by name and saw them grow up. When it was time to slaughter them we brought them to the butcher, got a carcass and the fur back. Guests could help feed the animals, feel the fluffiest pillow out of treated fur and I could tell them the name of the animal we served. However, most of them (obviously all meat eaters) could not comprehend at all, how we could slaughter and process those absolutely cute things.

I prefer to know where my meat comes from. Many people prefer not to, so they can loose appetite or get upset if they see the animal before it is brought to the butcher.
