None of those points actually back up your statement that it’s misinformation. No matter the diet, imbalances or excesses will be bad for your health.
As for health benefits, do they compare to an “average” diet, or an otherwise healthy one. E.g. a “Mediterranean diet”? It’s also worth noting that a vegan diet, without planning, will lead to deficiencies. Ultimately, our bodies evolved to run on a mostly plant based diet, with a small amount of meat supplementing it. It’s what allowed us to oversize our brains so much. If you choose to alter what you eat, that’s fine. I also agree that most people eat way too much meat. That doesn’t mean going to the other extreme is better.
As for carcinogens, we are constantly dealing with various types. Burnt bread is technically carcinogenic. Our bodies have evolved to deal with them. Too much, and you’ll obviously overload the repair systems and cause issues. The same can be said for a poor/deficient diet however.
