You cannot stop kids from drinking...just like you cannot stop kids from doing drugs. What exactly do you mean by taking responsibility and act like an adult? I didn't see anywhere in that persons post about saying it's okay for kids to drink. I agree with their assessment that if you or old enough to die for your country then you are old enough to have a drink. But that doesn't mean I think it's okay for 16 year olds to be out getting hammered
