Folks can argue, intelligent creatures! But its not clear how that makes a difference. And it sounds like an argument made up after the fact - "How are we going to criticize eating pigs?"
How 'intelligent' is a hive of bees? How 'smart' is a creature in its own environment? No, its only human-like intelligence that matters. Again, what's emotionally cute and fuzzy.
