One of the many imbecile Christian doctrines -- there are so many -- is that the financial obligations of the husband should be perpetuated after divorce.
Non-Christians do not want this.
So, now the question becomes:
How do we prevent the Christians from enforcing their imbecile views onto non-Christians?
You cannot argue with people who believe in imbecile doctrines, such as Christians.
That is why the only solution consists in resurrecting the 6th Department of the Soviet OGPU.
We must follow the lead of the French and Russian Revolutionaries. As Voltaire so beautifully put it: "crush the infamous", i.e. "Écrasez l'infâme".
