Take into account that one of the basis of my theory is that animals have no rights per se. When thinking about it it seemed illogical as it's impossible to police, control, or even tu conceive. How could you give rights to some invertebrate living 50 foot underground with a lifespans of 3 days that won't even see a human in that time?
My ideology thinks about humans. I'm human. Society is form by humans. Humans are the only rational being on earth. We can work with humans.
My definition of cruelty and why avoid it is not based on reduce harm to animals, I don't care about that. It's based on reduce harm on humans. That's why the intention and the enjoyment of causing suffering is the thing to avoid. Because that's what create "bad" humans, "cruel" humans. Humans that will hurt other humans. That's the only reason why I think that cruelty (towards anything, animal or not, even alive or not) is to be avoided. Just as a way to create a better society for humans.
As long as humans are "good" and not hurting other humans I don't really care if animals suffer. They are "lucky" that cruelty towards animals is proven to make humans worse. But just farming and managing livestock for human consumption has not been proven to do that, as there's not cruel intentions in it. Just intentions to feed ourselves.
