When there is discrimination, there is always difficulty getting through it.  But the issue is not simply one of instilling a different mindset toward the discriminated, which is hard enough to do.  The issue also has to do with the fact that discriminators fear retribution for their actions should the discriminated get fair compensation.  This cycle of discrimination and distrust can be overcome by instilling a different mindset in the next generation, but relying on this entails no justice for the current one.  And no justice for the current generation entails slower change, if any.  This cycle can be broken, but there needs to be a perception of fair-mindedness from both sides.  In some areas progress has been made.  It is usually best made when we accept our differences as much as highlight our similarities, and each side recognizes compensation as fair.  Freedom is not Justice, but it is a healthy attitude to take the opportunities given. They can be compensation enough.
