Read "The Moral Landscape," or, if you want the 15 minute overview, see Sam Harris' TedTalk on the topic, then come back to this discussion. If you still have no interest in the conversation here, admit so without comment.

Ok subjective morality. It is usually expressed according to whichever group specifics as moral.

I can get behind vegetarianism, especially if you eliminate higher mammals from your diet. But vegan has always struck me as daft especially when so many animals exploit us in a symbiotic fashion. A vegan who gets on my case for eating honey but guzzles almond milk which kills billions of bees is just a self righteous hypocritical prick by any other name. And there's the other class of vegan who seems to do it just to be contrarian or belong to an in-crowd (like many flat earthers) - I rather think they sneak bacon and beef jerky when we aren't looking (like flat earthers use GPS and planes navigating on great circles).
