I'd also add to the discussion that the reason why Norway (and I think Iceland too) eat it as "tradition" isn't because it's some sacred animal or traditional or something, it's because up until very recently both countries were dirt poor and neither country is particularly great when it comes to arable land that you can grow veggies or animals on. Whale is a physically big source of red meat that lives not that far off the coast, and has tons of other uses besides food too. They're also small countries so using them as a food source isn't that damaging (hell I'm pretty sure out of the entire Norwegian fishing industry the whaling part is probably the least environmentally destructive part of it)

Also grilled whale is like, really nice. It's like if tuna was a red meat.
