Why don't we just leave them to their business, and keep to our own? Otherwise, we'll have community organizers signing up dolphins to vote in elections and lobbying for tax dollars to fund flipper-accessible housing.
We don't do that now, do we? We pollute their environment with the raucous and confusing noise of cargo ships hauling goods back and forth across the oceans, drowning them with fishing nets, harvesting their food to eat ourselves, capturing them to amuse us with their tricks, (the Japanese) harvesting them for "scientific research" (aka, eating them), etc? Let's face it, they can't beat us OR join us...so they're well and truly frakked.
How come everyone's going so slow if it's called rush hour?
