Anyway, here is "official definition" from wikipedia:
> Since 1988, The Vegan Society gives two definitions of veganism:
> Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals.
> — The Vegan Society, Definition of veganism, https://www.vegansociety.com/go-vegan/definition-veganism
> The first definition by The Vegan Society is accepted among ethical and environmental vegans and the second definition by The Vegan Society is accepted among dietary vegans.[88]
So I am not "dietary vegan", I am "ethical" and "environmental vegan". I only agree with the first definition.
