Look at my teeth! I am a carnivorous HUNTER! I stalk the dangerous plains of... Albertsons... with a sharp knife I forged? bought! at Wal-Mart so I can run drive home and enjoy memes. Eating meat is my natural state!
Humans are omnivores by default and we're not even that good apparently at digesting grains or beans. Tell me more about how veganism is your natural state.
Oh it's not. But I feel like you are missing my point by assuming I think it is? As a concept, "natural" overrated, meaningless and not worth striving for. Both of us wear shoes, most people wear glasses and the majority of us travel by car. None of that is "natural", but if you are gonna cite that as a reason to eat meat then why not also go walk through the woods barefoot and nearsighted as well? Nothing about our modern medicine system is natural (but it makes us live longer), traveling to the moon isn't natural, heck the two of us talking over the internet isn't natural (but a net connection brings us both radically more knowledge than we would've had generations ago). Very little of our lives are so, why should this be a metric to care about?
But at the end of the day everyone should be way more concerned about scientific data, reason and logic than something as nebulous as living "naturally".
