my first comment . Gregs ' first ? <| sep |> So , you seem to have one argument and one link to why it matters . You start off by asserting that people don ' t kill each other disregarding wars , murder , genocide , and occasionally cannibalismSecond , you somehow come to the conclusion that animals are as smart as us . Your analysis is shaky to say the least . This begs the question why do animals eat each other if they ' re so smart ? I think it ' s because morality is localized and the net benefits of eating meat outweigh the harms , the animals eat meat . To make this example simpler , think of having a dog , and killing a flea because of the inconvenience to your dog . The idea is that some rights are prioritized above others
