There was an uproar when the right hand enabling act came into law.
The lefties reeled in disgust that their left-handedness was being outlawed. Was the world to return to the persecution of all the left-handed folk?
The right handed, found a new righteousness in their attitude to all things right handed. The evangelical right handed pointed out the right hand of God as being far more virtuous than the left.
The ambidextrous were prevented from all sport, left-hand drives in cars were to be corrected to right-hand drive never mind the chaos that might generate.
Over time people lost the use of their left hands and arms. They dangled as another appendage, and some of the virtuous had them removed.
Human dexterity waned as people realised the limitations of one hand only. Performance being rewarded by the sound of one hand clapping only went so far.
It began the time of the resurrection of the left hand.
