An 18 year old living at home does not exist in the disciplined environment of one in the military. An 18 year old living at home, while another 18 year old is donning a uniform to defend his country, may not be the 18 year old I'd want in possession of a gun.
That’s why I hate the “old enough to serve” argument. It’s just not apples to apples. I just don’t believe it’s a fair comparison. not that I think the age lime should be changed, or even in place, I just like better arguments than that one.
The problem with minors is that maturity doesn’t happen over night, or at the same rate for that matter. So it does make sense to slowly allow more rights as they get older, because we get more mature as we get older. However the problems with that is obvious to…. Like which rights and when and to who. Also you’ll have the constant question of “so I’m old enough to do A but not B?!” Which is a far point.
An alternative is simply all rights ar available on which ever birthday the government decides, we’ll say 20. Obvious problem right out the bat, that means we’ll arrest someone 19 years & 364 days old for doing something that would be perfectly legal in a couple days. That doesn’t seem reasonable either.
Their is also the option we chose, I’d call it a convoluted mess that makes no sense, follows no logic and is frequently politically driven. I’m not claiming to have any answers, I also acknowledge the system we have isn’t likely to change much at all, an age limit here or there maybe, but a honest thoughtful solution, well that’s not the world we live in.
All that to say, the fact is young people fight in wars, always have always will. And yeah, if you take a teenager and put him through boot camp, give him/her training and essentially put them under government control, I think most people would be good with that person, owning a gun, buying alcohol, tobacco and voting. We’d likely grant them a waver. But the real debate is about the other 98+% of teenagers. So let’s just have that debate honestly.
