The other thing to keep in mind is the demand for whale meat has sharply decreased. Japanese would rather eat beef. If you want to eliminate whaling, do so with economic tools. I.e. cheap beef.
Lastly, if you find you are anti-whaling but love a juicy steak, I consider you a hypocrite. They're both mammals. I've never seen any conclusive evidence that whales are any better than cattle. All the 'intelligent' behavior I've ever seen reported of is comparable to other animals 'intelligent' behavior that most have no issues of eating.
