I really didn't want to get into an argument on veganism, but your statement above is so incredibly wrong, I feel like I have to respond to it. You might want to read the very first page of the Bible, where God gave mankind our diet, and that was God's intent for all creation - not violence and bloodshed, but peace and harmony between humans and animals, and a healthy, natural plantbased diet. That's how it was in the Garden of Eden (see Genesis 1:29-30) and that same world of peace and nonviolence is again clearly stated in the prophetic scriptures, like Isaiah 11:6-9 and Isaiah 65:25.
So both the beginning and the end are perfectly clear. Peace and harmony among humans and animals. And in between, in the here and now? Does God want selfish exploitation, cruelty and needless brutal killing? No, absolutely not, and anyone who thinks otherwise is woefully mistaken. There are tons and tons of verses that tell us how God wants us to live...to do ALL things in love (1 Cor 16:14) to be MERCIFUL, (Luke 6:36) peace and gentleness (Gal 5:22-23) as opposed to needless violence, selflessness (1 Cor 10:24) and living by the Golden Rule. That is how God wants us to live in the meantime, in this fallen world. Not to embrace the callous violent temporary practices of this fallen world that were never part of His true intent for all creation.
I think where you go wrong is that you seem to think of veganism as only a diet. But it's not a diet, it's a choice to not harm animals unnecessarily. From a Christian standpoint it simply boils down to choosing MERCY. So to say that mercy is not a virtue of Christianity is as upside-down and backwards as it gets. Mercy absolutely IS a virtue of Christianity, that should go without saying.
Peace be with you.
I am ignorant on this Biblical diet topic, so please view any of my silly questions and comments from this perspective!

. ( I do need to now spend time studying it)
After reading your post and a couple of others, A thought popped in to my head, and maybe a real silly thought...
-----------
I wondered if eating from the tree of knowledge of good and evil that Eve, then Adam ate from, was actually us choosing to eat meat, and not just a vegan diet? I know it does not say that in what we are reading today in the Bible....
Why the thought came to me, is I was watching some documentary on human brain growth and science is claiming that when humans began to eat meat, our brains grew in size and we humans became much smarter, more KNOWLEDGEABLE.... And the story of eating the forbidden fruit, (yes I know it says fruit) from the tree of knowledge, might actually be describing when humans began eating meat and becoming smarter, more knowledgeable and this was original sin that we inherited....
With knowledge of both good and evil, after eating this forbidden food and God not wanting us to be more knowledgeable...and not just a biblical story about disobedience they had with God by eating some fruit they were not suppose to... Yes, they disobeyed God, but without further discussion that I as a layman am aware of, of God really not wanting us to become knowledgeable of the evil part of the Good and Evil? And by eating meat, is the point when science says humans had great advancement in knowledge?
Is this all mumbo jumbo....? Are my conjectures making any sense?
---------------------------
I am a meat eater...and boy do I crave and love it! Especially beef and chicken!
However, since the hubby and I have moved to rural Maine, we spend our time with all of God's creatures on a daily basis, we've befriended many different wild species, not just deer, and even from a distance watching how animals take care of their young, and each other as a heard or pack, and as a family unit....gives both of us a sense of awareness of God's creations and beauty....almost goose bumpy!

.
Just little things like a racoon with 5 baby raccoons, teaching them to crawl on her back, so she could cross the main country road in to the woods on the other side, then only to let them down once crossed to follow her again like little ducklings.... HOW did she know to do that...? How wonderful that she did know! All kinds of beautiful things like that from all of the creatures in the woods!
And every day we watch live, what viral you tube videos show on nature in amazement and aw, and constantly say to one another....GOSH! We don't know shit from shinola, about all that goes on in them woods and God's creatures. And hubby just mentioned about how cruel humans are on slaughtering animals that we eat.....
So, in our ignorance we both questioned if we should only be eating Kosher meat....wasn't that God's way of killing his creatures humanely??? It never crossed our minds that maybe we should not be eating meat at all...we never heard of such a thing being Biblical....and until reading it in this thread, I never knew there was even a Biblical argument and debate on it....
Where does Kosher come in?
