No, we're NOT wired for them.
This is from someone who actually studied evolutionary psychology.
In a nutshell: humanity has spent millions of years evolving in a very hostile environment (Africa's savannah), and to adapt and survive, early humans had to form tribes of hunter-gatherers.
Remember, humanity started millions of years ago, agriculture and civilization started only 10k years ago. (or 40k to 6k ago, if you really want to nickpick)
To survive in this hostile environment, filled with lethal threats, and with low ressources, was an everyday life or death challenge.
As a result, we are wired for fear, hatred, tribalism, snap judgments and so on. (it also made us resilient and strong, eventually landing us the top spot on the food chain as a species)
That's only a very short summary.
I have no desire to discuss the validity of this theory with strangers on the Internet. I've got other plans for my Sunday.
But I will readily provide ressources in moocs, books, videos if asked politely.

A good starting point for it explains the pros and cons of the theory in an accessible way.
