It's simply an indication of the lengths to which a controling, cultish, religious authority will go to control the actions, emotions, and thinking of others. When pressed regarding issues such as wearing jeans, members will often say it's only a small thing, why make waves. This is a giving over of ones reasoning ability to the authority of the leadership. While wearing or not wearing jeans may be no big deal, why is it so improtant to the leadership?
This type of control is practiced in almost every aspect of member's lives: Beards, extra curricular activities such sports or proms, the type of sex engaged in by married couples, the type of music and movies one listens to or watches, dress and groming as above mentioned... oh, and don't forget the use of pinatas, whether it's appropriate to tip your hat to a lady, etc.
Romans 14: 3,4 "The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condenm the man who does, for God has accepted him. Who are you to judge someone elses servant? To his own master he stands or falls. And he will stand, for the Lord is able to make him stand."
