Mink whaling is more responsible and sustainable than a lot of commercial fishing - compare the impacts of hunting a species that's classified as "least concern" with deep-sea trawling, the hunting of certain endangered species of tuna, or the use of the eggs and/or young spawn of endangered fish as caviar or whitebait!

Whaling definitely needs to go but (non-Antarctic) whaling gets an oversized amount of attention and it's not unusual for people who are opposed to it to be financially supporting even more destructive forms of kaimoana.
