Yeah I guess it comes down to whether something like "a vegan" is defined by action (not eating animal-derived foods) or by intent (attempting to not eat animal-derived foods because of religion, worldview, etc.). And if it's intent, are all vegans equally vegan? If I "eat vegan" for my own health, and you "eat vegan" because you want sustainable agriculture long-term, and Suzie "eats vegan" because her religion tells her to, are we all really "vegans?" And if we are, then why isn't a giraffe? We have no insight into its motivation, and "it evolved to do so" is a slippery slope.
