And then must we, through teaching, and through the more immeasurably important medium called example, show that such is not permitted. For such is something that is simply bad. Yes, and something evil. Something that is never even to be thought. And never ever to be done.
Taboos sometimes attach to such stupid thoughts that they seem silly.
Such taboos are useless and ignored when they touch disputed things upon which rational persons do not all agree. Still, some things in fact are wrong and bad. Without dispute, certain matters can be made taboo, things like killing your classmates and teacher at school on a fine spring day, or on any day. And all must agree this must be taboo, and never done, or human kind will not survive. So long as we blame the horror of that spring day at school, that murdered Littleton's children, on unmindful things like music, or tools, or lack of religious show, we invite terrible repetition.
