Point is, a great many people - even most, I would bet - wouldn't eat dolphins, on moral grounds, whereas the only compunction they have about tuna is whether or not we're fishing out the ocean.I have no problem eating Flipper. I've eaten mahi-mahi, as a matter of fact. ETA: not exactly dolphin, but I would eat dolphin if it was on the menu.
I didn't say "more learned" or "better educated," I said more intelligent, i.e., having a greater capacity to learn. An average newborn human is more intelligent than the smartest dolphin that ever lived.Also, our labrador retriever was smarter than our kids all the way up through their first year of life, and maybe even past that point. A dolphin probably is, too.
