“If the principle of nonviolence means*anything*, it means that you cannot justify *any* killing or suffering for transparently frivolous reasons such as pleasure, amusement, or convenience. And doing something ‘with compassion’ that is not morally justifiable does not change the fact that it’s morally unjustifiable.
When you decide what you want to eat, wear, or use, you are not acting under any sort of compulsion. You are simply indulging your palate pleasure, sense of fashion, etc., or allowing what is convenient to trump the interests of another sentient being.
So if you embrace nonviolence and you are not vegan, you need to think about what is unquestionably a serious inconsistency.”
