There was at least some justification in the old fashioned methods of learning and the first rule was to respect and obey your elders.
As the name implies it is learning it is not a battle of wills which it will become without that respect.
One small lesson from military training about both respect for those who through vast experience know better, and also of obeying an order without question or explanation.
"If I shout DUCK ! Do not ask why." It sure beats getting shot don't you think ?
Modern times, too much explanations not enough respect !
