The National Minimum Drinking Age Act of 1984, Which changed the drinking age from 18 to 21 is a form of ageism and a violation of Civil rights. Telling an adult 18 or over they can't drink alcohol, Is the same as telling a person over 65 they can't drink or smoke because they are too old.
Some scientists have came forward and stated the human brain doesn't develop until 21. That is anecdotal research, considering not everyone's brain develops at the same pace, and the majority of these so called "scientists" are funded by MADD. An organization that helped pass the law.
As our founding father Thomas Jefferson once said, "All men are created equal" not,"All men are created equal, except those between the ages of 18 to 21.
Please Mr. Obama, give adults there rights back.
