To tackle the modern controlled-demolition of marriage, and to highlight divorce AND contraception AND homosexual pervosex as the toxins, will not go down well among ANY people who do not make God the center of their marriage.
Truly, divorce/remarriage (of a valid marriage) is as evil as adultery (says Our Lord) and marital contraception is morally in the same league a buggery. They are both an intentional rejection of natural sex, natural marriage, and the grace which should raise us to the level of supernatural love --- that love for which we were made.
Excellent analysis in a nutshell.
In his homily today, our priest made a passionate defense of marriage in support of the Gospel reading. Very nice.
