One can validate oppression by acknowledging it and calling it what it is: unfair. One can own one’s legitimate anger over the oppression. Yet, if one waits to actually solve the injustice before forgiving, then those who are oppressing win twice: once with original and ongoing oppression and second by having the oppressed people living under a constant state of unhealthy anger or resentment. That resentment, over time, might be so strong as to destroy individuals and families within that oppressed community. Forgiveness without a correction of the injustice at the very least solves that one problem of destructive resentment.
