Of course, as with all the arts, everything is subjective and relative.
Speaking of relative, art, and food, here is a prime example:
Furor over horse meat on food show - Arts & Entertainment - CBC News
People are absolutely scandalized that a cooking show should feature horse meat! OMG!
This despite the likes of cows and pigs having comparable intelligence and social capabilities by means of categorization. You know, like cats and dogs.
