As a person who has gotten to kill a few pigs, I mostly agree with your sentiment. I am not outraged by the killing of a whale because of the blood. I am outraged because it is usually not done quickly or humanely, because often a B.S. reason of conducting "science" is used an excuse to fuel an industry, because some of the species of whales hunted are threatened or endangered (can't say that about pigs and sheep), and for the fuzzy reason that I think cetaceans are too smart to eat.
But whales aside...I understand where you are coming from.
