"Well, I'm not giving up dairy, but I can probably give up meat, and milk is at the very bottom of Brian's table of suffering per kilogram demanded, so I'd be contributing to much less evil than I was before. That's good, right?
"For all the unimaginably terrible things our species do to each other and to other creatures, we're not—we're probably not any worse than the rest of nature. Gazelles suffer terribly as lions eat them alive, but we can't intervene because then the lions would starve, and the gazelles would have a population explosion and starve, too. We have this glorious idea that people need to consent before sex, but male ducks just rape the females, and there's no one to stop it—nothing else besides humans around capable of formulating the proposition, as a proposition, that the torment and horror in the world is wrong and should stop. Animals have been eating each other for hundreds of millions of years; we may be murderous, predatory apes, but we're murderous, predatory apes with Reason—well, sort of—and a care/harm moral foundation that lets some of us, with proper training, to at least wish to be something better.
"I don't actually know much history or biology, but I know enough to want it to not be real, to not have happened that way. But it couldn't have been otherwise.

My wish for things to have been otherwise ... probably isn't even coherent; any wish for the nature of reality to have been different, can only be made from within reality.
