Actually, I suspect (but am not certain, hence the questioning) that this falls in one of those areas where some humans genuinely differ from others with respect to morality.

I think it would be illuminating to hear individuals who think it is too far down the slope to articulate 1) why they feel that way 2) whether the objection goes away if it's for organs instead of food, 3) how they feel about early-term abortion and embryonic stem cells 4) whether it is morally okay to eat a corpse of a person who has died and has given permission to have their corpse eaten.
