are old enough to be drafted should they ever reinstate one, old enough to be solicited to enlist in the military and be sent to war, can be tried as an adult, old enough to be sued, and have to pay taxes, you're damn well entitled to be able to enjoy a drink or a beer in this country too. Just remember the above and keep in mind you are old enough to be held responsible for your actions while you're drinking too. That's pretty simple I think.
Either that or raise the age equally on the rest.
Quit with the cherry picking.
