People never hurt others in moments of personal strength and bravery, when they are feeling good about themselves, when they are strong and confident. If we spent all of our waking moments in that place, then fighting for social justice would be redundant; we would simply have social justice and be done with it, and we could all go swimming, or fishing, or bowling, or dancing, or whatever people do. But it is because we spend so much of our time in that other place, that place of diminished capacity, of flagging energy, or wavering and somewhat flaccid commitment, that we have to be careful.
