None of the last paragraph is proven one way or another. The topic is not dolphins but even if they can use telepathy, are super smart and super awesome, if people want to eat them and it is done sustainably, then I see no issue with this. It would be hypocritical for me to say otherwise given I like eating other tasty meat products as well as wearing animal products like leather.
Alright, now I will start near the end of your post. I believe you have called out people you claimed knew nothing of the things they said in their lack of debate and yet only a few posts later here you are talking $h!t about something you obviously have no knowledge of. Dolphins have shown the ability to identify pregnancy less than a week after insemination, and I have a leather jacket with fur lining that is leather made from ranched non-reproductive steers which were also eaten and New Zealand possum fur that is an ecological pest!
If this is not part of the topic then why did you type the things I quoted in order to prove your point on the topic?
If man had not disrupted the balance of the ocean eco system, was not the harvest of each eaten species in harmony with all the eaters. Look at all the ecosystems of the planet. Without modern man they all seem to be in balance. The apex predators take the weak, sick and old; there is a sustainable cycle. Some not so evolved human societies have worked in harmony with nature, but industrialized man, who's medicine saves many that natural selection would not, over harvests and destroys the balance.
Wikipedia:I am firmly convinced that we shall become one of the greatest whaling nations in the world. The whaling grounds round Korea and Japan offer unlimited possibilities, and should stocks of whales, contrary to expectations, fail in those areas, we have the Sea of Okhotsk and the Berring Sea to the north and we are aware of the great treasure houses to the south. The day will come when we shall hear one morning that whales have been caught in the Arctic and in the evening that whales are being hunted in the Antarctic. [15]

Japan has a history of destroying the balance. If they could whale sustainable they would still be able to whale in their own waters. They stripped their own waters and now seek/have to whale elsewhere. They also contribute to the crash of the Tuna stock as you have pointed out. Why should their past and current failures lead to us letting them have their way? Isn't that a very similar question you ask over and over about the Sea Shepherd's?
