I'm a vegan anarchist, I guess that counts as a spiritual belief? No gods, no masters, no cages.

I suppose so, in the sense that I'm very much a physicalist. Given the lack of knowledge around consciousness and the similarities in biology between humans and other animals it is completely unreasonable to assume they don't suffer in a way that could very well be morally equivalent to how we do.

Not at all for me!

I'm an anti-theist, so for me it is about not hurting anyone that can suffer. Nothing more.

i'm largely asking because my Buddhism deeply informs my vegan practice. it seems logically consistent that to believe in the morality of not killing, that same morality should be applied as universally as possible, and thus also ought to apply to my diet. that kind of logic was instrumental in my "conversion" to veganism; applying that logic in various situations allowed me to make different choices which have eventually become habits/lifestyle that rejects killing as much as possible.
