So you want the most dangerous drug to become legal for persons who are still barely mature enough to understand the difference between right and wrong?
I find your argument weak on many accounts, the first being your clear need to have alcohol, yet you say you are not an alcoholic. Persons who don’t have the disease of alcoholism simply don’t care wether they have alcohol or not.
Furthermore, maybe check on the statistics of why the laws were changed state by state to protect young people. Your description of binge drinking is a perfect example of why young persons under 21 are not yet mature enough to consume the most dangerous drug on the market.
