Humans are wired to be tribal, but not necessarily racist. Early man was nomadic, primarily a hunter-gatherer. Note that at this time the races were still fairly geographically isolated. Spats were generally more like family feuds. We know this because early bones and artifacts are generally very similar genetically.
As humans progressed to a primarily agricultural existence, they began to draw boundaries and have conflicts between tribes. As their radius of influence expanded, they began to encounter peoples of varied evolutionary adaptation and we see the beginnings of defensive racism.
For those of you with a biblical paradigm, The old testament tells of the birth of race. While building the tower of babel, an undertaking that drew peoples from all over the middle east, Africa, and southern Europe, God injected multiple languages so that different peoples had a harder time communicating as the tower was a symbol of man's ability to equal God's accomplishments. What's interesting here is that race was a negative thing, essentially a punishment by God. If you are not under the mythical, magic spell of religion the question remains why this negative reference to the origin of race?
Race has, from its very invention been a weapon. The difference between races is genealogically insignificant. In fact, the things we associate with race, positively or negatively, are largely cultural in nature. Looking at the US, race has been used as a method of partied. "White" began as being defined as western European (primarily English). It then grew to include Germans, then Irish (the Irish, running from famine, were almost all debtors). The Italians found it extremely difficult to integrate and many looked down on them as thugs and criminals (at least until Hollywood made Italian cool). However, by the early 1900s, all of these variants were consolidated into the definition of "White American", forming a dominant racial majority that has been used to control the dispensing of resources and power.
There is an entire science for the study of race. I've spent a lot of time learning about it and talking to experts in the field of study, mainly because I am a history buff. You will realize "the game" and look at everything differently. For those who are against critical race theory, it is essentially a commitment to looking factually at our history. Not teaching it is a commitment to racial whitewashing (pun intended) to maintain a racial advantage.
Corporations now have proof that integration leads to higher performance and profits. A study showed that companies with good racial diversity significantly outperform companies that don't. MInority economies in the US (Black, Asian, Native, etc.) fall right behind the major western nations in financial power. I'm not sure how the WS plan to put all of that back in the box and still compete with China.
