Our current development, specifically our Brains, is due to cooking and consuming animal flesh.
We've advanced to our current level of intelligence and our current sophistication of society because we learned how to cook the flesh of animals prior to eating them.
We may now be able to adjust our diets to remove most of the consumption of animal flesh by substituting other items, but to what end? If our goal is to bring about the decline of humanity or reverse the advancement of humans, and also society and civilization as a direct consequence of such a goal, then perhaps your personal belief is warranted.
From my point of view, right or wrong, I see no point in adjusting my diet to satisfy an ideological belief, and I prefer to continue to follow the diet that has improved the human race.
Good luck with your beliefs. You are welcome to them.
Nodding my head, tapping my cane, and stating ‘Here, Here”!
Neanderthals ate raw meat. Then discovered fire. Learned how to make it on demand. Learned that cooking the MEAT was tastier and far easier to digest.
What they did not realize was the protein from cooked meats and fats enlarged their brains and enabled them to advance their intelligence.
That is why I refuse to be a vegan.
I do not want to digress.
