I'm not necessarily denighing ADD, but what about children with problems in controlling themselves and part of it being biological/chemical problems?
I knew a guy about 19 or so who could not control himself at work. He would just constently talk and swear without any control over what he was doing. I was told later from another friend he had ADD or ADHD and that he refused to take his medicine. When he would, he had much more self control.
He is also not banned military service, owning firearms, nor gaining security clearance for any contracting whatsoever with the government.
Drugged, he is an emasculated, pacified, sheepish tool for those who control his condition. That is the antithesis of self-control.
