18 vs. 21

It doesn't make sense to me the differences between the privileges a person gets from the time they turn 18 and the time they turn 21.

Think about it, when a person goes to college, most of the time they are 18 years old. When you turn 18, a lot of things become a available for you. When you turn 18 in the state of Florida you can:
1. stay out as late as you want (no state curfew)
2. gamble (in certain casinos)
3. serve alcoholic beverages (in most places)
4. sign your own permission slips (if you're in high school)
5. purchase cigarettes
6. get a loan (not only academic ones)
7. vote
8. get a credit card/debit card
9. get a permit for a handgun
10. enter a/work at a strip club
11. purchase pornography
12. join the military
and the list gos on and on. But, out off all of the things you do when you turn 18, you STILL have to wait until you're 21 to:
1. purchase alcoholic beverages
2. gamble (everywhere)
3. serve alcoholic beverages (everywhere)
4. enter a lounge
5. go to clubs (everywhere)
6. go to Vegas (and actually do stuff)
7. purchase the handgun (but you can buy a riffle, shotgun or ammunition at 18)

This doesn't make sense to me. At 18 years old, someone can enlist into the military and put their lives on the line for their country, but they aren't allowed to drink some beer. They can purchase porn and even be in it, but they can't go to any club they want to? And the thing that gets me the most is at 18 you an both serve alcoholic beverages and purchase a handgun permit BUT, you can't consume alcohol nor can you purchase an actual handgun but you can purchase a riffle, a shotgun and/or ammunition. None of this makes sense to me.

According to Edgar Snyder & Associates Law Firm's website, in 2008 out of 2,978 car accident deaths, 875 (29%) of those deaths were caused by drunk driving. In the United States, teens (16-20) were the cause of 17% of car accident deaths while under the influence of alcohol in 2008, and young adults from the ages 21-24 caused 34% of car accident deaths while under the influence of alcohol. So, 18 year old young adults can serve 21 year adults alcoholic beverages who then go out and cause more deadly accidents and kill more people while driving impaired than people who drink underage (16-20)? I don't think that's fair.

The Department of Treasury and the Department of Defense wrote a report titled A Report by Gun Crime in the Age Group 18-20 in June 1999, and they reported that 18 year old young adults accounted for 8% of all arrests for murder which makes them the most dangerous of this age group. They then go on to say that, "[a]mong murderers, 18-20 year old [are] more likely to use a firearm than adults 21 and over." However, they never mention any statistics proving this supposed fact. And, if this fact is true, then why are 18 year olds still allowed to purchase a permit for a handgun but they can only buy a riffle or a shotgun? What makes a riffle or a shotgun any different from a handgun?

So, what really grinds my gears is just like people fought for equality between gender and equality between race, someone needs o fight for equality between age. Its not fair that 18 year olds can only receive half or partial privileges, nor is it fair that the privileges that they do receive aren't balanced with the privileges that they will receive only 3 years later. Chose one age for all of the pillages and don't split them up.
