I actually explicitly address this one in the fic. I'm starting to doubt that you've been paying much attention.
I remember you addressing why a butchering facility is impractical. I don't recall you addressing why it's morally acceptable to hunt animals but not morally acceptable to hunt humans; if you did and I missed it, then I apologize sincerely, as that's solid evidence I wasn't paying attention.
What I'm talking about is not the Scottish method of making a blood pudding out of a butchered animal, but the Maasai method of bleeding a cow- essentially similar to the European method of milking cows or Canadian method of collecting maple sap. Since they're doctors, they'd use syringes instead of arrows and plugs, but the basic idea would be the same: have a 'dairy cow' whose relevant organ is their marrow, not their udder.
They already considered this, but dismissed it, when it came to humans- they would be able to get the blood without killing, but would lose the benefit of calming animal blood.
(Since I'm thinking about this, the way I'd introduce it is not Bella thinking "wait, why are we killing them when we don't have to?" or suddenly being interested in animal rights- but as a product of a debate where Bella raises the issue of vegetarianism with a human-eating vampire and the human-eater (particularly if it's one that buys blood to consume, rather than killing) points out that Bella's really not any better than the human-eaters or humans in general, and asks why they don't put their morals into practice and abandon hunting- which Bella might then adopt as a great idea.)
She made mistakes, which stemmed more or less directly from flaws in her personality, and bad things happened.
I think the two main things that bother me about her mistakes are that, as far as I can tell, they come from flaws that you introduced and those flaws are unrelatable. Bella's flaw is that she thinks that assassinating the world government is a good way to go about things (another way to think about this flaw is she considers politics more important than people). What's the moral, here? Don't try to assassinate world governments? I already knew that one, thanks.
What's the deeper moral? If you're vapid, the consequence is spending eternity telepathically beaming love at your husband, who is overcome by emotion and distracts you with the physical manifestation of that love. If you're thoughtful, the consequence is spending eternity bound to a pile of ash while every day your husband's ghost eats your liver anew. Why choose to rewrite the Prometheus myth?
The reasons I give for not having a butchering facility apply to any other facility that would keep domestic animals. The animals would still need a place to live that would be hard to pick up and move when the vampires got suspiciously youthful-looking for their claimed ages. Also, if the vampires were trying to keep animals alive, they would suck at it. The poor cows would die of stress from having to be around them.
As for your other criticisms: I'm sorry you aren't enjoying the story I have chosen to tell. That's a pity. I suggest you don't waste more of your time on a story you don't like. Hopefully you will be able to find something more worthy of your attention.
In the vein of the Harry Potter and the Methods of Rationality discussion threads this is the place to discuss anything relating to Alicorn's Twilight fanfic Luminosity. The fanfic is also archived on Alicorn's own website <strike>(warning: white text on black background)</strike>.
Previous discussion is hidden so deeply within the first Methods of Rationality thread that it's difficult to find even if you already know it exists.
Similar to how Eliezer's fanfic popularizes material from his sequences Alicorn is using the insights from her Luminosity sequence.
Spoilers for the fanfic itself as well as the original novels need and should not be hidden, but spoiler protection still applies for any other works of fiction, except for Harry Potter and the Methods of Rationality chapters more than a week old so we can freely discuss similarities and differences.
EDIT: Post-ginormous-spoiler discussion should go to the second thread. (If you have any doubt on whether you have reached the spoiler in question you have not.)
