That article looks to be over a year old. Subsequent info on dolphins since then include they recognize themselves in a mirror (as do elephants – who mourn their dead btw) and it also turns out dolphins have names – they identify themselves with particular consistent clicks and call each other by those same names. That being said. If those scientists want to grant “human rights” to cetaceans there is other stuff to consider. Its not just gonna be all about free cute Flipper from captivity and warm and fuzzy feelings all around.
How we damn near wiped out whales from oceans of the earth. All that oil we used to light our homes and power our society, The blubber and bones and everything else we WORE – eeeww so that was all human being stuff we used?? People have a hard enough time coming to grips with what we do to actual humans, they aren’t going to get behind adding even more crimes against humanity to their karmic roster.
Buuuuut since dolphins are assholes, including Elon’s dolphin son *nod Coqui* I suppose they’ll all rally behind this cause, and sue us all for past enslavement and reparations and leave the whales out in the cold. Cuz whales aren’t cute and smiley.
