Speaking only for myself, I think self-defense and aggression are entirely different. Inasmuch as aggression is a choice, the aggressor alone carries all ethical and moral weight. People who defend themselves against aggressors have no ethical or moral boundaries whatsoever. More simply put, ethics do not apply to the enslaved or the persecuted – never did, never will. Not only must enslavers carry that burden alone, but their descendants must also carry that burdensome legacy, until they make amends, or their bloodline vanishes from this earth.
