What theoretically sets people apart is the knowledge that this phenomenon exists. We can actively choose to be different. And we must.
Or we're back to war, holocaust, and likely the destruction of life on this planet, because our weapons have wildly outstripped our intellectual and emotional development as a species.
While this is true and what @Box hauler described is factual. It's something hardwired into us as humans. It's part of our nature. We're really just highly intelligent apes after all. Different is suspicious and possibly dangerous. Just like wolves from one pack for an example, will have a different scent from another. As a means to help tell them apart from one another. One smells like pack, that other one doesn't. Run the interloper down out of our territory, or kill it. Or both. Humans do this also, though our noses aren't as powerful as other animals. We instead rely on looks and instinct as a determination for our prejudice. Fear is a very powerful tool often utilized by humans and other animals alike as a mean of survival. The whole fight or flight response. We really haven't evolved from that, its a primal lizard brain function.
Having recently been to the UP, Marquette specifically, towards the end of last year to visit with my SO's family for the holidays. I felt completely out of place as there was no one like me seen when we ventured out. Though I at least wasn't shown any outward bias, I definitely got some stares and whispers. They knew that I was black, but also that I was a city boy, from how I dressed. I didn't look their part wearing Nike shoes, puffer jackets and Adidas track suits. I would even subconsciously find myself looking around for another black person as a mean of recognition, safety and comfort. I got over it, but it was still an initial response to seeing a lot of people that didn't look like me and were of a completely different look, feel and culture.
This part of human nature is no different than women, LGBT's and other POC's on college and university campus across the country, wanting their own "safe" space where they can be around others that identify the same as them. Or look like them and not having those that are "different" invade their space. Likewise racial groups like Black Culture club, Persian/Arab Culture club, Gay Pride club, Hispanic Culture club. Women's groups, etc. It's unfortunate that we as humans verbally claim to want diversity and an end of segregation in society. But as a whole we tend to also consciously, or subconsciously prefer segregation as a simple means of identity, culture and feeling of belonging/acceptance and safety. It's really just psychology 101.
