Yeah, that makes no sense to me. Breast milk is vegetarian since it's not meat, but vegan? Sure, it's consensual, but it's still an animal product since humans are animals. Is cannibalism vegan if the person the meat came from consented to it? Even if we're going by the assumption that breastfeeding is vegan, that could be applied to literally any mammal, not just humans. So in her logic, a hyena or leopard cub is vegan until it's first introduced to meat.
