You can’t just throw out the word “human nature” and expect anyone to accept it. “Human nature” just means “this thing we all know about how the world and people work, come on… now don’t be difficult”. It means nothing.
We are biological beings and our biology determines our diets, neurology, endocrinology, and multiple other factors about our lives. Whether people like it or not, we do have a biological human nature that shapes many aspects of our behaviour and culture.
