Pardon me for fighting you on this, but I believe you are incorrect. You’re abdicating your responsibility, in assuming that those animals will always be killed.
Put it this way. If you lived next to a chicken farm, and drove over there any time you needed a chicken, and watched them kill it for you, would you have any qualms about saying it was killed for you? Why does having it go through a grocery store first somehow change this? However you get your meat, those animals were still killed for your benefit.
The average American eats about 250 pounds of meat in a year. That’s a bit over half a cow, or about one and a half pigs, or somewhere north of a hundred chickens. That’s the butcher’s bill, directly attributable to the average American. So to take your own words - yes, if you stop eating meat, exactly one pig will not be killed every year. Around one and half, actually.
