But...here are the problems I see. First, as Mike notes "Obviously some of the marijuana and cocaine users also could be binge drinkers, and some of the rage guys are fueled by alcohol, so we will have some overlap."
Very true. But I strongly suspect abuse of drugs and alcohol is fairly intertwined; that is, folks who abuse alcohol will alos tend to abuse drugs--whether it's coke or meth or prescription meds such as painkillers or anti-depressants.
Second, Mike assumes such problems are normalized evenly across all segments of society. They are not. Instead, the preponderance of such issues tends to occur at the fringes. Think about it: are you more likely to have anger issues if you enjoy a satisfactory social and professional life or if you feel there are unknown forces constantly conspiring against you? Isn't one who lacks self-esteem and lives in constant irrational fear more apt to abuse alcohol and substances?
Third, stupidity and clumsiness. Probably an issue that cuts evenly across society. However, we're not talking about operating a toaster--we're talking about handling a deadly weapon. As we know, very few gunloons are adequately trained. Those who receive training usually do so from folks equally inept to safely handle firearms.
Bottomline: The true numbers:
Alcohol and/or substance abuse: 35%
Anger Issues/Mental Illness: 15%
Lack of training: 75%
Note these percentages aren't cumulative. But what they tell us is about 35% of gunloons should be disarmed because of substance abuse and mental illness issues. But the biggest problem is that the overwhelming majority of gunloons are simply unqualified to own a weapon.
