It may never be 100% resolved the tensions and history of behaviors, but I think it would be a cop out to throw hands in the air and continue to perpetuate the same claptrap. Someone has to break the cycle.
This is where PRIVILEGE comes in: as you said, it will continue on because it doesn't bother the people as much as it bothers minorities. There is no incentive to change their behavior over generations especially when the game is in their favor. Moreover, as they become more and more removed from the social injustices (because it is taught at acceptable throughout the generations, and substantiated with stereotypes,) the burden is heavier and heavier on minorities who go through the oppression everyday. Then, these same people who remain ignorant of this have the nerve to tell minorities to stop complaining while doing nothing to change their behavior.
So, when one reread this entire thread, it is easy to see these types of mentalities in full view. From complete denial to downright disdain substantiated with antedilluvian stereotypes.
If the time to truly understand the problem was utilized instead of ignoring it, pretending it doesn't exist or blaming the victims, maybe these people wouldn't feel like their "race" is under genocide everytime a family browner than a paper grocery bag moves into the neighborhood/sports/schools. That fear is due to guilt of consciousness, not "white" guilt. Indeed, it is projection, seeing as they were the ones who historically committed genocide upon several native populations around the planet.
