I'm going to cover several points on this and then lets hear what you all have to say.
For background information, review this short link of world drinking ages.

As you can see, the United States is relatively alone in having the world's highest drinking age. A vast majority of modern industrialized countries have their drinking age at 18, some such as Germany and France even go as low as 16, and 14 for Switzerland.
First point: What makes Switzerland's 14 year olds and Germany's 16 year olds more mature than the United States 18-20 year olds?
Common arguments (and for good reason) are if someone is legally old enough to have the following responsibilities: Die for your country, be forced to register for the national draft, pay taxes, hold jury duty, sign legally binding documents, get married, own a home, elect our representatives, adopt a child, and be held accountable for your actions, one should be old enough to have a beer after doing them.
Second Point: If you are Legally an adult, doesn't that mean you are old enough to drink?
The 21 year old age limit, although with good intentions, is not working. In fact it's a complete failure. Minors are still drinking in large. However instead of drinking in public areas like bars where they can be monitored and even have certain limits, drinking has been forced into the shadows and in privacy where it can't be monitored. Not only this, but we are forcing them to drink without any education on the matter. This lack of education is what causes immaturity and over indulging (binge drinking). Another problem is the 21 year old age limit is creating something called the "Forbidden Fruit Effect". Essentially, alcohol is mysterious and sexy to minors. It has been put on a pedestal and held over their heads above even military service and voting. This forbidden fruit effect causes 18-20 year olds to indulge even more on the rare chances they have access to alcohol, which can lead to poor decisions. Lowering the drinking age will take away that mystery that we are shrouding alcohol with.
Third point: Isn't the 21 year old age limit forcing our "minor"-adults into drinking in hiding where it is unmonitored and even more dangerous.
Essentially, we are making alcohol a bigger deal than it really is. What the government really needs to stress embracing it and treating it maturely so we can all enjoy it in moderation. Bring it into the home, open a bottle of wine during dinner, educate our kids on it. Some states make it illegal to allow their children to have alcohol even in the privacy of their own home. How are we supposed to educate our youth if we are banning things like this from the most important classroom?
Fourth point: Isn't the 21 year old age limit preventing any kind of positive culture change towards alcohol?
Some arguments suggest that drinking isn't even healthy for you, well these are entirely wrong. As a matter of fact alcohol in moderation can be extremely healthy for you. An article below goes into greater depth, but a quick overview consists of: Moderate drinkers tend to have better health and live longer than those who are either abstainers or heavy drinkers,
"In addition to having fewer heart attacks and strokes, moderate consumers of alcoholic beverages (beer, wine or distilled spirits or liquor) are generally less likely to suffer hypertension or high blood pressure, peripheral artery disease, Alzheimer's disease and the common cold. Sensible drinking also appears to be beneficial in reducing or preventing diabetes, rheumatoid arthritis, osteoporosis, kidney stones, digestive ailments, stress and depression, poor cognition and memory, Parkinson's disease, hepatitis A, pancreatic cancer, macular degeneration (a major cause of blindness), angina pectoris, duodenal ulcer, erectile dysfunction, hearing loss, gallstones, liver disease and poor physical condition in elderly."
Yes the list sounds quite amazing but it all can be found in the article and well sourced by Prof. David J. Hanson, Ph.D.

Fifth Point: Despite what you may think, moderate drinking is actually healthy for you.
The government gave the states an option, either A) Raise the age to 21 or B) The Federal Government will cut federal funding for highways as a penalty. Essentially this is blackmail. It may seem like a lost cause, but what may surprise you is that some states are actually considering going back to the 18 year old drinking age regardless of the threat by the federal government to cut funds.
