"They usually swim 100s of miles in the ocean and now they are just doing laps in a pool."
-This isn't anyone's exact quote, just a simplified version of what I think the animal lovers are getting at.
It's a whale, it doesn't care. It's swimming 100s of miles because it such a large animal it needs to swim that far to find food. The man made "pools" in zoos and aquariums is what wild whales dream that heaven is like.
"Whales are smarter than most animals..."
- again, this is condensed animal rights phrase.
There are obese humans who have their family bring them Cheetos so they can spend the rest of their lives in bed watching TV. When they eventually die the city needs to take out a wall of the house so they can remove the body.
Yes those people have bellow average intelligence, but all jokes aside, they are still smarter than whales.
I believe animals feel pain and animal abusers should be punished, but I don't believe animals are upset over being fed, given companionship and receive medial treatment, no matter how small their new home is.
Domestic dogs are believed to have evolved from wolf-ish animals that chose to give up the forests for human scraps.
I believe whales in captivity are happier. If the "seconds before the attack" video is legit, that whale looked content. The problem wasn't that it was upset, the probelm was that it's a dumb animal that didn't know it was killing it's trainer.
