I'll qualify this post by noting I'm not familiar with this particular species of dolphin. But there are a couple of major differences between most dolphins and animals that we hunt, especially grass eaters like deer. For starters, dolphin are one hell of a lot more intelligent than deer, and most other animals too. For another, they have a really strong affinity for humans. The many stories about them saving folk who have fallen overboard, pushing them to a beach, etc. are true. For whatever reason, dolphin seem to just naturally like us humans. I can personally attest to the fact that if you are in a boat and get even remotely near a pod of dolphin, they will generally come right over to your location, within inches, jump and play around the boat, look you in the eye, and just generally say hello. Everyone I've ever met (and I'm sure most that I haven't met) that goes to sea loves dolphin and would find the idea of killing one repugnant.
The fact that "liberals" self righteously pretend to be lovers of creatures they probably never see in the wild nauseates me. But so does the wholesale slaughter of these beautiful creatures. Anyone who takes pleasure in it or finds it funny ought to ask themseves if they'd also take pleasure in or laugh at the slaughter of the other animal that love humans, the dog.
And I'll add to my post 39 that while hunting "game" animals like deer is supremely thrilling and even magical, the taking of the life of another living creature should never be taken lightly.
