Opinion and truth are two very different things.  A decision made after searching and praying through an informed conscience will always outweigh peoples' personal opinions, and with regard to contraception, the book is closed.  The people have indeed spoken.  The trouble with the other issues mentioned here, and interestingly they are all "pelvic issues," is that the bishops prohibit the sensus fidelium to enter into their deliberations and pronouncements.  This makes their decisions incomplete and non-binding because the whole Church has not entered into the process.  Under these circumstances, the only thing the People of God can do is trust that their own conscience formation method is open to the direction of Holy Wisdom.  And move on.
