Not all of them are endangered. I think reasonable hunting of f.ex. minke whale is perfectly fine. But I do think that whale hunts should be limited to the waters of the nation that does the hunting, that international trade in whale meat should be disallowed, that the hunting should not be opposed but well regulated and governed by an international body that is unbiased by either those that wish to hunt as much as they can or those that think whales should not be hunted at all.

Besides, the intelligence of a species should not really dictate whether it is to be eaten or not.

What is much worse than the hunting is the cetacean bycatch, because that is largely ignored, in particular the right whale bycatch that the US is responsible for.
