No. You should lock up your kids if they’re so stupid as to play with guns.
Guns and the NRA are not the problem, it's parents, schools and authorities that have made boys into shadow girls, made guns into something other than a tool and refuse to discipline or properly treat mental aberrations when they are identified.
Not only are children not allowed to engage in age old role playing games with guns, they are vilified and punished, even if heavens to God they draw a picture of a gun.
Once upon a time when boys were allowed to be boys, when guns and their proper use was taught and not vilified, we didn't have school shootings like this because the boys were allowed to settle their differences in short fights that rarely resulted in serious injury. So don't blame the NRA and guns, put the blame where it truly belongs, the Dr. Spock lunatic, flower child, pussified liberals that have screwed up our kids until this inevitable result has been achieved.
