You mean people like, oh farmers and butchers say. Well, I guess you move in different circles to me then.
I would say the evidence goes fairly close to 100% against that opinion. People who really know where their food is from are very happy to eat it.
"Why do we eat animals, Mummy": Because they're so tasty, also we can digest meat.
"Why do we eat chicken, Mummy?" Because otherwise the fox would. If we were herbivores then our teeth would be different and our bodies wouldn't make the enzymes to digest it.
"This fish didn't want to die for us, Mummy": I don't think fish are very good at thinking, but it's tasty and we can be appreciative of the food we have.
When my friend went vegan after watching the sad cows. " X, not only have I milked cows for money, I've breastfed my kids- stressed mammals don't give milk."
I love that almost all of the 'evidence' you use to refute opinion is basically opinion!
Yes humans can digest some meat but we can't survive on meat alone. Meat-only diets can cause protein poisoning, we can survive on vegetarian-only diets, but meat alone can kill us - we're not that adapted to it.
Grizzly bear diets are about 70-90% vegetable, pandas almost 100% - they definitely have carnivore dentition. Humans have nowhere close to true carnivore dentition (see all those flat grinding molars you have, and the lack of carnassial teeth) so you tooth example is basically bollocks. At best we have poor omnivore teeth.
"I don't think fish are very good at thinking" - so that would be your opinion then? Based on...?
Dairy cows have been highly selectively bred for high yields and will produce way way above natural milk yields even when stressed. Though their yields do improve when unstressed, to say they don't produce when stressed is hugely flawed - have you done any reading on the stresss response to maternal separation in cattle. No thought not.
To me it sounds like you're pretty deluded about human biology and also where your food comes from. So you pretty much proved the PP's point!
