Is this culture?

Yeah, unfortunately it is. But there's a difference between traditions and ingrained cultural racism.

Is there a difference between the whale killing and this?

Is there a difference between continuation of traditional practices of food sourcing and culturally acceptable racism? Yes, definitely. Does that make culling whales morally acceptable? Of course not.

I think maybe the concept of culture being this unchangeable thing that transcends humanity and empathy

I never said that, though I can see how what I said could be perceived that way.

Yes in that culture, preferably after stopping the cull.

Some communities survive an entire year on a single whale hunt. Look, I understand why you're so incensed, it's horrific. But it's pretty privileged to judge other cultures by your personal standards and morals.

For what it's worth, you seem to be completely ignoring the fact that I've been saying this whole time that it SHOULD BE STOPPED. But to say that without knowing if those whales may be the only main food source for an entire community is pretty ignorant.

Check yourself. You can be disgusted and angry and disappointed with this and still understand that it may be a requirement for the survival of these people.
