There is a common thread which runs through divorce, abortion and euthanasia although it is not one of 'cause and effect' - it is that many people consider them all immoral, whether they are legalised or not.
Libertarian, irreligious, secularists discount this common aspect for a very simple reason - they do not want to wage their anti-Church battle on more than one front at a time.
The type of divorce that actually results from their efforts is indeed a rabta ċoff (i.e. not binding at all) par excellence because it enables spouses to worm out of their responsibilities towards society, each other and their children by a common consensual arrangement for a 'no blame', 'no conflict' divorce with the law courts becoming involved only to determine the sharing of the spoils.
I am glad that he no longer discredits St Thomas More as a strong advocate for divorce but only after it was pointed out to him that Henry VIII actually beheaded him for his lack of enthusiastic support in securing a divorce from Rome.
