Oh, I wasn't intending to comment on the discussion you were having with the GP, just to point out a small flaw in reasoning. But since you asked, no, it does seem rather arbitrary. I'm not sure where you wanted to go with that argument. I would not eat dog, but I happily eat pork. I don't have a rational explanation for why, but neither do I care enough about it to want to try to change it. If I did, I would probably go in the direction of eating dog rather than to stop eating meat entirely. It would not take much to push me in that direction. A few weeks in Korea might be enough for me to get over it.
