This is not at all what Veganism is.
Veganism is LITERALLY an ethical stance regarding exploiting/harming/killing non-human animals.
Finding a random blog online that states otherwise means nothing. Anyone who ate a salad last Tuesday these days thinks they can simply decide what Veganism is.
THIS is the actual definition of Veganism, directly from the people who coined the term:
“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."
Vegan here. I approve of this message.
