Originally from Canada, now in the USA. I've noticed palpable distrust and hatred on both sides of the street. Its not just that whites are racist against blacks, its the total breakdown of trust on both sides of the coin, leading to social exclusion. Just as a black person may have trouble breaking into a white man's only club, a white person would have no possibility of entering black only spheres w/o experiencing racism as well. IMO the only solution is deeply intentional integration such that all classes and colors begin to experience all aspects of life together, ultimately including marriage and child birth. Until we see "them" as "us" there will be allegiances.
