Double edged sword. The irresponsibility of young drivers is well known. So how does that help the gun argument? Maybe we should take away their cars? It's been argued.
Also, one can argue that rifles and shotguns are more important in a sporting paradigm. That is not a major reason for handguns (yes, folks do handgun hunt).
Be careful with this sort of argument. If it is that they misgbehave with Y so they should have X to misbehave with, that is not a winning argument.
