The Catholic Church does not marry divorced persons nor does it marry people who are not Catholic. I don't recall the Church being sued for this. The Church does not ordain women to the priesthood and yet it has not been sued for this. SO please stop with the fear mongering and ridiculous argument that the Church will be sued when marriage equality becomes law. That has not happened in the places where marriage equality is law. If all you can offer is misplaced fear you will never win an argument in court. No wonder more and more people are supporting marriage equality.
