I have always believed if you are deemed old enough, and mature enough to be given military grade weapons, and told to go fight where our government sends you, and possibly not come back, then you are old and mature enough to drink! If you are responsible enough to hold military grade weapons, you should be responsible enough to hold a beer! I have seen older men, act like idiots, and under age people act far more responsible. I don't think 21 and older has anything to with being responsible, no matter what you are doing. Drink and get stupid, pay the price! But if you are old enough to fight and possibly die for your country, or whatever other reason, our government deems, you should go, then as far as I am concerned, you are old enough to drink!
