I think the general idea he's getting at, in short, is basically that, even though so many arabs and jews seem so very consumed with hatred for each other. Likewise for many blacks and whites. (Oh, and by the way, meanwhile, for all their charms, many Japanese people have a tendency to hate those from outside Japan.) Or consider further the russians, whose very souls are consumed by just hatred for the Arabs, Jews, Whites, Blacks, Japanese, all of them and then some. Basically everybody. That's a whole lot of hatred even before you turn your mind to the consideration of the innumerable religious wars fought the world over. Its constant wars over land expansion disagreements. Its, "Hey, buddy, how about fuck YOU for gunning down my prized pig, asshole!?"-type wars, which is actually a real example OP plucked from the annals of history, believe it or not, though OP did admittedly simplify to just the broad strokes of the matter. I think the gist of what OP is conveying is very simply this: our planet is seemingly overflowing with all these wars, all these murders, all this hate deep in our hearts and souls and minds. To the point that we're beginning to see a glut of shootings happening at schools, of all places, once known as places of learning for future generations of minds. And these shootings are conducted not even by hateful adult Russians (with a notable exception or two), but by literal minor children who've yet to reach the legal age of adulthood. That creates an impression that, in this crazy world, we are experiencing hatred practically from the womb, or at least birth, all the way through childhood and into pre-puberty, continuing without stopping straight on into your puberty years, your young adulthood, middle age, your so-called golden years, only arguably stopping when your lifeless body is crudely fitted with an ol' pine overcoat, at whatever age that may happen to be relevant to you. Here we get to OP's main point, which is that, if you turn your focus now to capybaras and ask, "Who do you hate?" You'll find the answer, perhaps much to your surprise, is that they do not hate anyone. They really seem not to have a care in the world, if you observe them. To the point that it would probably be a futile gesture to attempt to bring a spirit of hatred into the presence of these guileless and benevolent creatures. They wouldn't know what to do with it. They have no concept of it. Why would you do this? Most likely, the maximum rise you're going to get out of a typical capybara is that it might decide to go hang out with its friends, which include ducks, cats, cows, and anybody else. They're just ultimately not that persnickety when it comes to socialization preferences, since they are really just wanting to find a nice spot to relax and unwind, ultimately, and they hope you'll join them, unless you have hatred in your being, in which case, see above where I talk about their views on that. They're not fans, in short, if you don't want to go back to read about it again. OP seems to be suggesting, and I'm probably inclined to agree generally, that every human living on this dawned beautiful blue marble might be able to glean lessons from the way the capybara conducts itself, if we were capable of humbling ourselves sufficiently. Also if you ever find yourself about to kill another person, for any reason besides LEGITIMATE self-defense, then you’re an asshole. Unless they’re a billionaire. OP is pretty sure all of them have it coming for the misery they willfully inflict on others for profit.
