Abridgement of the age of majority
The drinking age is the lone exception to the legal age of adulthood in the US. 18 year-olds can vote, enlist and fight in Iraq, enter into binding contracts, marry, own businesses, serve in judgment on a jury and a host of other rights and responsibilities. In nearly all cultures, alcohol consumption is coincident with the legal age of adulthood. Legal Age 21 is out of step with the generally accepted societal norm of alcohol as accompaniment to maturity and adulthood.
