If Carroll would reread Humanae Vitae, he would realize that Pope Paul VI was an astute prophet. All of the cautionary statements in the encyclical have come true. I remember how all the secularists declared that Pope Paul VI was a nut case to predict such dire warnings against the decoupling of the sex act from procreation. PPVI said that homosexuality would come to be declared normal sexual activity as well as abortion on demand and the lessening of the importance of marriage. Since birth control became the rule of life for most of humanity, the linking of sex with procreation, love and marriage has come full circle. The only purpose of sex has become enjoyment as a recreation. There is no longer any significance of the sacredness and power of the act within marriage which brings forth children.
The result is all sorts of dysfunctional behavior, rampant sexually-transmitted diseases, broken homes, impoverished children, etc..
I wish people like Carroll would really read the encyclical in light of a history of about 40 years since its publication. He might actually have to pause and admire PPVI instead of trashing him.
Carroll, as an ex-priest, has an axe to grind with the Church, and re-reading the Pope's encyclical would be unlikely to open his eyes, I fear.
Time has made many of the '60s and '70s radicals older, grayer, but not wiser. They're still having an "authority problem".
