I wonder why folks [most often Christians] feel the need to apologize for for the actions of their group, although they themselves did not perpetrate those actions. While well meaning, such an apology is self-serving; one seeks to personally rehabilitate their group, deserved or not. And it would be presumptuous for another to accept such an apology, unless s/he is an aggrieved party.

The rules for apology and forgiveness are simple: only the perpetrator can apologize; only the direct victim can forgive on this earth, and God in the hereafter.

I only apologize for my hurtful actions; I don't speak for men, white men, Americans, my co-religionists, or family members. I don't forgive Christians, Arabs, Jews, Nazis, racists nor mass murderers (as a group)...but I would forgive You for a wrong done to Me if you apologize for Your personal action.

If you feel that you can actually right a wrong, that is the best apology you can make for your group.
