Can you state a positive thing that comes from animal abuse?

The lack of a positive doesn't make something morally wrong.

-You can't trust a society that will off you if you ever end up disabled

The "trust" thing is a rather weak argument. I think society would continue to function if disabled people were "euthanized." Societies in the past have. Besides, what if it's a genetic disability that I'll never get? Then I don't have to worry.

A society works best when all it's members are in a healthy mental, emotional, and physical state.

Um, that sounds like a Utilitarian argument that we should kill permanently disabled people to me.

How do you think killing the disabled effects their mothers, their families?

How do you think eating animals makes vegans feel?

Sorry, my arguments are somewhat aggressive. I should clarify: I'm not attacking you. I'm certainly not defending animal abuse or forced euthanasia. I'm not even defending vegetarianism. I think there are plenty of good arguments against it…I just don't buy your ethical system.
