The younger you are, the more likely you are to shoot someone, or be shot by someone else your own age:

Ceterbis paribus, it is then prudent to restrict gun ownership, especially handguns, to young people.
If we know that the younger you are, the greater chance there is of you getting shot by someone your age or you shooting someone else, then the higher the age for ownership of handguns, then there will be fewer young people getting shot.
So I've used evidence to prove my point, lets see if you can as well.
How many 18-21 year olds use or require a handgun for self defense? Does the benefit of having a gun for self defense outweigh the evident increased risk from owning a gun at such a young age?
This is something you now have to prove.
No, I don't, but nice straw man attempt. I never argued whether the benefits of whatever percentage of 18-20 year olds having the ability to own handguns outweigh the rationale against it. I simply stated that, just because you don't see any benefit does not mean one does not exist.
Thanks for playing.
