I'm not willing to be legally responsible for your ass. It's not my job, I'm not your dad.
And no matter where you are in the military, someone Legally Responsible made a decision and they have the right to enforce those decisions by Federal Laws.
The simple question you must ask yourself in civilian life; are you legally responsible for yourself or not? Under 18, the answer is no. Who is responsible? Your parents.
Not your brother, not a buddy, not a stranger.
Even simpler; if you cant legally vote, you are not legally responsible or accountable for yourself. Someone else has to deal with the consequences of any of your decisions.
It sure as hell wont be me.
