You might prefer to argue that it's an accepted anthropological truth that humans have incisors that aid in cutting, there's no more science to back up the argument that incisors evolved to cut the flesh of an apple vs. the flesh of other animals. It's an assumption and presumptuous to theorise that the incisor evolved for flesh eating. The truth is neither of us can ever know. That's the pseudo-science.
So yes, incisors cut, it doesn't mean that you have to eat animal flesh, apes don't. They crunch ants with the same molar teeth we would, if we ate ants. If you think they do to the contrary, you probably read too much into planet of the apes. Yes I appreciate the irony in combating your pseudo-science with my own. I find it more intuitive that plant based diet is more natural than a 100% meat diet. There's too much propaganda and misinformation for vegan vs. meat diets. The middle ground probably makes sense, but there's lots of studies that say that even a little meat is bad for you. So typical advice that everything is good in moderation is probably not quite good enough, more likely we should eat ratios much closer to the apes, than typical modern westernised diets. I eat meat/diary, but minimize it as much as possible.
