Diversity of opinion, beliefs and behavior is rooted in instinct diversity, intellectual capacity, the language(s) we speak, the religions and ideologies we are born into, our family of origin and birth order, gender, differing and competing social norms, all these things make us different from one another.
“Celebrating Diversity” is an excellent virtue, but social groups will continue to resist tolerating murderers and rapists. How we deal with murderers and rapists will vary. Always has, always will.
Our task as individual primates is to figure out where we fit in.
Our diverse instinct packages, our large brains, and our relative lack of hair were factors in the survival of our species. They will continue to do so long after you and I are dead.
