21 or 18?

in my opinion it is unfair for an 18 year old to be considered an adult but not be allowed to consume alcohol. i believe that if the person is able to vote, be drafted, smoke cigarettes and forced to serve jury duty should be able to consume alcohol. i am not saying that they should lower the drinking age to 18 i just think maybe we should consider these factors. if the government doesnt want to lower the drinking age why dont we raise the other laws. it is not fair that tomorrow i could be drafted to go to war but i couldnt go to a bar and order a drink. if im not mature enough to drink alcohol how could i be mature enough to vote!!!!
