To me the whole problem is fascinating. I can very easily understand the idea of not wanting to kill personally, but how does one jump to not eating pre-killed meat, and especially to things that processed to the point where they don't look like meat at all such as sausage or salami? I mean, I understand that there are a handful of efficient utilitarian altruists who care about what the outcome is for the animal and now how doing the act feels for their own purity, but I would figure most people rate actions based on how they feel. And chewing pepperoni pizza does not feel the same way as a grimy, messy, bloody pig murder. I guess I am just surprised how many people think like utilitarians, caring about the outcome for the animal, instead of what I would think the more natural, namely avoiding to do actions that feel too gruesome but happily enjoying the results if others do them.
