Omnivore is ambiguous?

It’s a pretty clearly defined word in context, our teeth have evolved for the use we put them to. Apes eat vegetative material and flesh. Mostly vegetative, little bit of flesh. That’s a pretty common ape trait.

That is beside the point of veganism and if it is moral for us to do it now that we know better, it just simply is a fact of nature.

Your thoughts do not care about what our bodies evolved to do in nature. You can use your teeth for whatever you like now.

There is no concept of veganism outside of humanity and that’s fine.
