I think the whale hunt should be limited because of the few left in the oceans not because eating whale meat would be ok or not.
The whale hunt must be limited or even stopped for maintaining the species balance in the ocean.
Same goes for the shark hunting mostly because of the wrong image people have on sharks and because for wanting their fins etc.
That you got spammed by those greenpeace people, I think they have overreacted, since you are neither a whale hunter nor an politician who wanted the whale hunting.
But the claims that many foreigners have against Japanese eating whale or Chinese, Koreans eating dog meat etc. is nothing more but a cultural ignorance.
I mean, when it would be cruel to slaughter and eat whale and dogs, do pigs, cows, chickens etc. deserve to be killed and eaten then? Are those animals less worthy to live?
Anyone who eats meat should not criticize that much about other culture's cuisine.
