Oh wow. Let me try forming that argument: 1) meat is nutrient-packed and getting all your nutrients from a plant based diet is stupid hard 2) to be able to be a vegan and healthy you need (today at least) to be in a privileged position (how many poor vegans do you know?) 3) we evolutionarily got here by eating meat - our bodies do better when eating animal fat and protein. The grown and thriving survival of our species is anchored in killing other animals (sounds f’ed up but it is what it is).
