Nice straw man.

Women do exercise leadership in the Church.  One does not need to be a priest in order to lead or have authority.   In many dioceses today it is women who have the ear of the bishop and often exercise positions of high leadership in dioceses--whether they be Chancellor, Bishop's delegate to X, directors of offices, etc.  This is the same in many parishes.  It is women who have the ear of the pastor even over that of the assistant.  

Being a priest isn't about power or even authority.  Though priests do exercise authority, the priesthood is about the exercise of FATHERHOOD.  There is a reason priests are called "Father."
