I raised a pig last year, didn't do anything to it I wouldn't have done to or eaten myself. Well, with the exception of putting a bullet in it's head. Anyway, I decided if I couldn't buy a baby, raise it up, treat it well and slaughter it myself I had no right eating pork. I felt like I needed to earn that right instead of just walking into a store and buying whatever all neat like in a package.
It turns out I had no troubles what so ever with any of that so I eat pork with a clear conscious now.
It's not something I wanna do again really but it also isn't something I would avoid. If I had a bigger family and enough wasted food to feed a pig I would keep one for that reason all the time.
