Knowledge isn’t bad, and I’m aware of where I’m knowledgeable and where my limits are. I tend to be quite a bit more knowledgeable about philosophy than the average person, most people don’t introspect or read about where truth comes from. They often don’t even know or understand what an axiom is, even though they’re foundational to how we live.
If that’s all too much for you, you can literally just disregard my latter two paragraphs before you went into your defensive panic. I don’t (usually) need to get into the idea of normative truths to justify veganism, because ironically we live in a country of “animal lovers”, many of whom would happily literally kill dog abusers. I’ve unironically met non-vegans that advocate for the fucking death penalty for people who abuse dogs.
That amount of dissonance, to advocate for actual death for humans who abuse animals, while themselves literally paying for animal abuse, is sufficient to dismantle people’s entire preconception of animal rights and worth. If we happened to live in a society without massive hypocrites, where people consistently held that abusing and torturing all “lesser” animals was okay, I’d have to get into more nuanced discussion about the nature of truth to help people get to veganism.
