alt Hacker NewsJust because you evolved to do something doesn't provide a moral justification to do that thing. Whether you evolved to or not, animals suffer extraordinarily in the farms of torture we've made for them. It is well accepted that you can eat healthily on a vegan diet, and it would only really take a couple articles to figure out how to have a healthy plant-based diet. You could do it at Walmart.
Who's moral justification? Yours?, My families?, my community?, my government? my god?
I maybe too much of a individualist, so I get a little triggered when I see claims from others about the moral justification of what I should eat, what job I should have, who I should vote for... When these things that I do are not hurting myself or other humans.
Now I'm sure you could take an example of each one of these and "butterfly affect" to some example of hurting another human, but I could do the exact same thing to any one of [your] lifestyle choices.
