A minimum standard of decency
I am a vegan because it is the minimum standard of moral belief, behavior, and attitude regarding nonhuman animals. Speciesism is the same underlying wrong as racism, sexism, and heterosexism, only in a different form. The speciesism of our society is extreme, and that is the only reason veganism is not widely considered a minimum standard of decency.
