For men who have children, their duties as ministers might detract from their responsibilities as parents. Instead of teaching their children important life skills like how to make a wiener-roasting stick, they would be off at some committee meeting or preparing a sermon. Thus these unfortunate children of ordained men would almost certainly receive less attention from their male parent. According to the Genesis account, men were created before women, presumably as a prototype. It is thus obvious that men represent an experiment, rather than the crowning achievement of creation.
Men are overly prone to violence.
They are responsible for the vast majority of crime in our country, especially violent crime. Thus they would be poor role models, as well as being dangerously unstable in positions of leadership. In the New Testament account, the person who betrayed Jesus was a man. His lack of faith and ensuing punishment stands as a symbol of the subordinate position that all men should take. It is expected that even ordained men would be unable to withstand the natural male tendency to buckle under pressure.
