You ask great questions. Humans are naturally tribal and so there is a natural tendency to "pick sides" and then attempt to dominate the other side. Look at team sports, how often is the other team dehumanized to justify winning at any cost.

Meanwhile, perhaps you can explain why the Nation of Islam gets some "sexual charge" out of taunting and demeaning Jews. One would think having been victims of identity politics, they would not do the same to others... but that would be wrong.

So, because humans are naturally tribal, we need to combat tribalism by integrating. Integration begins with laws against discrimination. But frankly, laws can only go so far.

We need to promote social integration. Look how naturally people of all races unite when placed on the same team and facing an opponent. Once people begin to socially integrate, many will move to the next level and "pair off" producing biologically mixed offspring, like my children and grandchildren.

Because the US is constantly adding people, we will never be fully integrated, but we need to make that the goal and move towards it.
