> Well, what's the problem with eating, say, gorillas, if done in a sustainable way?

There's no problem with eating these animals if it's a cultural norm. Many indigenous peoples in Africa, eg the Bari of Sudan, eat monkeys and other apes. Whales have been hunted in Canada by aboriginal peoples since time immemorial. It doesn't matter how smart or social you are. Someone or something unsympathetic is going to eat you, and it just might be humans who don't share your (actually our) ethical ideas.

I like the dish "Whale bacon". It's pretty un-PC, but would eat again.

I wish christians not to regulate all over the world in their way.

I'll happily bite that bullet: in principle there is nothing wrong with eating gorillas. Or whales, or dolphins, or whatever other non-human species we're projecting onto today.

I don't draw the line in the consciousness-of-the-animal dimension. I draw the line on the life conditions of the animal dimension.

There's nothing wrong with killing gorillas and eating them as long as we don't imprison them for life in overcrowded farms like we do with chicken, pigs and cows.

Killing animals while they're free in their natural habitat is fine, or at least it's 1000x better than what we currently do.

At current catch rates it's very sustainable.

Whaling is much more humane than industrialized animal farming.
