Well, if you don't eat meat at all then you would be upset by it - especially after seeing the pretty goatling at the top of the feature
Otherwise, it's like eating 4 month lamb, 8 week chicken, 9 month rose veal. Maybe those who are upset by it don't know the realities of meat and milk production, and think that if they weren't eaten by us all the little kids would have a long and happy life skipping around in green fields, rather than having their heads stuck in a bottle of gas at birth, or whatever method is used to euthenase them.
