I think "Father" well encapsulates who a pastor of a parish is and what he does.  He is the spiritual head of a family who is responsible for the spiritual and material needs of a parish.  I would not object to "father" being limited to pastor's and all other priests given another title like "don".  I also see the reduced number of women religious as contributing to this.  When you had healthy religious orders who could staff schools there was also a "Mother" who was a powerful feminine witness.  With their collapse, we are only left with male leadership.
