I&#x27;m responding directly to an argument based on it being morally wrong to kill living things, specifically to kill some living things but not others (cows but not golden retrievers).<p>I am not making arguments against veganism, i am asking a philosophical question in response to a moral position.  Please understand i am not attacking you or your lifestyle<p>My argument was, again, how do you use a moral justification of &#x27;killing things is wrong&#x27; to change from one lifestyle of killing things, to another lifestyle of killing different things?<p>Why is cow vs golden retriever so important, but golden retriever vs potato completely laughable?  You are still ending life to nourish your body no matter what.  Both a cow and a potato cause and have external costs as well (i would say methane from cows is less or equally concerning as pesticides)
