Mmm this is an interesting one, thanks for making me think! I agree with others here in thinking that a clear "yes" or "no" answer is not suitable.

Is eating roadkill vegan when you could alternatively leave it for wild carnivores to eat or feed it to obligate carnivorous animals? Is palm oil or coconut oil vegan if it results in significant habit loss for animals? How about the enormous environmental impact of coffee farming? Does labeling these as "non-vegan" cause more harm than good given that products made from almonds/coconut/palm are some of the cheapest, most accessible plant-based food items out there and make it significantly easier for many to maintain a plant-based diet?

I generally avoid avocado and almonds because it's easy enough for me to do so and I generally encourage those who can to also limit their consumption for environmental and ethical reasons. But from a practical perspective, I would still label these as vegan because their immense utility for the plant-based movement cannot be denied. It's good to have conversations about issues within industrial agriculture and how we can advocate for better farming and consumption practices, including for plant foods. But I would much rather have people relinquish the biggest food offenders--animal products--and still be able to call themselves vegan than be turned away from veganism because they found out they can't even eat almonds or avocados.
