As someone that lives in the artic I must disagree. I'm not really sure how serious you are since you compare it to eating babies and whatnot, but it's not any more barbaric than eating any other animal.
Unnecessary hurt to the animals is just that, unnecessary, of cource. Here in norway we don't pratice clubbing to my knowledge, I can't imagine so at least since we have pretty strickt rules for animal rights (an animal police and stuff as well).
My friends that live on farms used to have cows and sheeps as pet animals, and they are amazing and cosy animals just like seals. But in the end they as every other animal breed for meat was slaughtered. If anything I think you have a very limited view on animal rights if you think that one kind of animal should be protected because they are nice, as if that wasn't the rule with almost all of them. Good to see that you care about animal cruelty though, but that's a very different story than commercial seal hunting. It's also important to understand why different cultures do what they do, and not just write it of as something idiotic right out of the gate.
