Not Truly a "Free" Adult at the age of 18

Exordium:
In America you can go to war and take some's life away at the age of 18. You can vote on the next president of the United States for the next four years at the age of 18. At the age of 18 you are technically considered an 'adult'. You can smoke cigarettes, view/buy porn, buy lottery tickets, all at the age of 18. The drinking age used to be 18, but for unclear reasons to me the drinking age has been increased to 21 years of age. People who support this law believe that 18 is too young and that 18 year olds are not 'mature' enough. Or when someone under the age of 21 is in a car accident because they've been drinking that's another thing that leads supporters on and makes them push that the drinking age should be 21. Those moms that lost their child to a drunk driving accident are the main people who push for the drinking age to be 21. It's hard to judge if someone is 'mature' enough; and just because a few dumb people my age have gotten into accidents does not mean that all people under 21 are bound to do the same thing. A drunk driver could be 45 years old and crash and die, and some people take 30 years to mature. You cannot shelter and limit everyone just for a handful of other people's mistakes. Now, I'm not arguing this because I want to drink and because I'm not old enough; I've managed to live 19 years without drinking and I think I can handle one more year. But if today I went to the Army and enlisted I could join, go through basic training, then be sent somewhere else for more training, the kind of training where they teach you how to take someone else's life. So if we're talking about killing people, drunk drivers sometimes kill people, but 18 year olds in the military are purposely trained to kill. A life is a life, it doesn't matter if one was accidental or on purpose, or if one 'deserved' it because they're the 'enemy'. This argument is obscure because for some people who have lost a loved one due to drunk driving I'm sure it is a touchy and rough situation, something I'll never understand. But as it goes for being an 'adult' at the age of 18 and you're allowed all these freedoms like enlisting, buying a lottery ticket, buying cigarettes, we are still restricted from drinking.



Narrative:
The drinking age should be 18, not 21. In an argument the strongest way to present this case would be the delivery. Any Joe Smith could say this, but if this argument came from a soldier who is back from war, after seeing death and possibly having a hand in it, he comes back to the States and he can't even get a beer.


Partition:
The drinking age did you use to be 18, but as of late too many people are scared of their own shadow; they hear a story about a 19 year old drinking and accident in the same sentence and they freak out. If one 19 year old drives drunk, well damn we must all do. Another case that is argued against the drinking age being 18 is that young adults are not 'mature' enough yet. They think that since 18 is only two years after getting your license, that's not enough time to understand all your responsibilities.

Peroration:
There are many freedoms that are available to us when we turn 18, one of the most important of them is being able to vote. We get to decide who the president of the free world is, that's a huge responsibility for an 18 year old. Being able to enlist and being able to vote are two huge responsibilities that are so easily accessible to us as soon as we turn 18, yet we can't enjoy an alcoholic drink every once in a while.
