Why not, Cub? Is it because you don't want to see him cave in to the left? Who gives a ? This isn't the same America as 50 years ago when Joe and Bob could park the ol pickup in a grocery store parking lot, sporting a full gun rack, and nothing would happen. The modern America is one that it's in the middle of an addiction and mental health crisis, where 95% of children are taking some form of psychotropic meds by age 10, while they watch a "media" that is constantly looking to stir the pot and incite discontent. Do you think the modern America is healthy and responsible to own guns as they once had?
No, I'm not saying to gun grab, but to still allow firearm purchase at age 18 is nuts. 18 now is not 18 then. If you bought your son an air rifle at 10 and he promised you he'd be real responsible with it and then you caught him shooting out the neighbor's windows, you take the gun away from him until he's old enough to respect it. Until then, he's lost his right until you deem him mature enough. The "son" in this case is the modern US of A.
