Here is the problem. All these nasty things you speak of such as racism are all variations of tribalism that is hardwired into the base ego of all of humankind. Only a highly developed intellect allows individuals to rise above the primitive impulses of fear and hate the “other.”
Some have an inherent level of intellect that allows them to be inclusive and some gain it through high levels of education. But you can bet that at all times at least half the population of the earth will want to wallow in the fear and hatred of the other. And now that the United States has a president that by his deeds and words says that’s a good thing, strife is being given a huge boost.
