But still, nobody really claims to appreciate the pork the schnitzel he enjoys in the cafeteria used to be. It is much easier to get emotionally engaged with a living being when you see it and interact with it in its natural environment and you are the one who kills it and watches it die, than getting emotionally engaged with the beef where the frozen meatloaf you bought from the supermarket comes from.

"Pork" and "beef" are only used to describe the food items. I don't think being unwilling to acknowledge that the food you eat once came from living pigs and cows makes you morally superior to someone actually involved with the process.
