In all cases, were talking about killing animals that are known to be highly intelligent and social. Nobody should be killing them.
I mean, that applies to plenty of the animals that people breed/hunt for food without outrage.
I'm fond of whales (and rorquals in particular), but my opinion has always been go big or go home. Bar the question of sustainability/conservation, whale hunting isn't inherently any worse than rearing livestock or other regular forms of obtaining meat - personally I think the only rational stances are to oppose all or oppose none.

Further, they where doing it under the auspices of research far from Japan vs Norway which was more brazen, but also more local.
PS: Alaskan whale hunting by Inuit also largely gets a free pass.
